The US Securities and Exchange Commission (SEC) has held discussions with Everstake, one of the largest non-custodial staking providers globally, to explore clearer regulatory definitions around staking in blockchain networks. The meeting, which also involved the SEC’s Crypto Task Force, comes at a time when over $193 billion in digital assets are staked across major proof-of-stake (PoS) networks. However, despite the massive scale of participation, staking remains in a legal gray zone in the US as regulators wrestle with its classification under existing securities law. The previous SEC administration also took enforcement actions against major players such as Kraken, Coinbase, and Consensys due to their staking services. The agency, under pro-crypto President Donald Trump, has recently d…

A man from Wellington, the capital city of New Zealand, has been arrested in connection with an FBI-led investigation into a global cryptocurrency fraud operation that allegedly stole $450 million New Zealand dollars ($265 million). According to New Zealand Police, the man is one of 13 individuals charged after authorities executed search warrants across Auckland, Wellington, and California over the past three days. The charges stem from allegations that members of an organized criminal group manipulated seven victims to obtain large amounts of cryptocurrency, which was then laundered through multiple platforms between March and August 2024. The US Department of Justice has indicted the man under federal law, including charges of racketeering, conspiracy to commit wire fraud, and conspirac…

Panama City Mayor Mayer Mizrachi has hinted at establishing a city-level Bitcoin reserve in a cryptic post following his meeting with two of El Salvador’s Bitcoin policy leaders. “Bitcoin Reserve,” Mizrachi wrote to X on May 16 after meeting El Salvador-based Bitcoiners Max Keiser and Stacy Herbert.

According to a May 15 statement from Paraguayan prosecutor Irene Rolón, the men were caught by police soon after breaking into a locked section of Teratech SA’s facility in Coronel Bogado, leading to their arrest. Prosecutors believe the men may have had ties to Teratech as independent contractors, but are still waiting on official confirmation from the company’s CEO. The three deported were Chinese nationals Jinping Duan, Tian Jianyun and Zheng Guanglong, who did not have official entry records into the country. Paraguayan authorities and Interpol believe the men illegally entered through Brazil or Bolivia. The thre…

Key takeaways: Traders expect a Bitcoin price pullback to $90,000, but a bull flag could break out to new highs if profit taking near the range highs reduces. On-chain data suggests the current profit taking is too weak to extinguish Bitcoin’s current price momentum. Bitcoin (BTC) price has spent the bulk of the week pinned below $104,000 to $105,000, which many analysts have labelled as a resistance zone, but an alternative view suggests that BTC is simply consolidating within a bull flag. A bull flag is a continuation pattern that is characterized by a period of sideways price action following a sharp uptrend, and when the structure confirms or breaks from the trendline resistance, the uptrend continues.  BTC/USDT 1-day chart.

Successfully hosted a static portfolio using S3 + CodePipeline, documented the entire flow, fixed initial errors, and gained hands-on AWS experience. "Show your portfolio using S3 and CodePipeline." That's what the interviewer said. And guess what I did? I half-did it — only used S3, completely forgot about CodePipeline. Classic fresher moment. But I didn’t stop there. After some caffeine, chaos, and clicking around AWS documentation like a lost tourist, I figured it out!

What is a parallel public chain? The transaction execution of traditional smart contract platforms (such as Ethereum) is serial: one transaction can be executed only after the next one is executed, and even if the transactions do not affect each other, they cannot be processed in parallel. This leads to a very low throughput (TPS). Ethereum has an average of only a dozen TPS, and transaction congestion and gas fees soar during peak hours. Parallel public chains are different. They analyze the dependencies between each transaction and execute independent transactions on multiple computing cores at the same time. In layman’s terms, it is to make the blockchain multi-channel parallel operation like an assembly line, split the tasks into small pieces and process them in parallel, which can gre…  ( 6 min )

This turned out to be a pretty cool concept. While working on my site monitoring app, I had around three or four services like uptime checks, DNS lookups, pinging, and a few others. Since I’m not much of a UI designer, I ended up creating separate files for each service, even though they all shared the same layout. That’s when I discovered Flask’s template inheritance. Instead of repeating the same code over and over, you can create a base layout and reuse it wherever you want. It really helped clean things up and made everything way easier to manage. Here’s how you can set it up. template-inheritance home about contact Then, in your child template, you extend the base and override that block: {% extends "base.html" %} {% block content %} hello world!! {% endblock %} That way, you get the shared layout and can customize parts of the page without repeating your code.  ( 3 min )

🚀 What Are Generics in TypeScript? When developing applications, we often need flexibility while maintaining type safety. TypeScript’s Generics solve this challenge by allowing us to create reusable components that can work with multiple data types. In this guide, we’ll break down generics step by step, ensuring you fully understand how to use them efficiently. Without generics, you would need separate functions for different data types. For example: function returnString(value: string): string { return value; } function returnNumber(value: number): number { return value; } This approach leads to redundant code. Generics solve this problem by creating a single function that works for all types. Generics use a placeholder type, such as , allowing a function to handle various dat…  ( 5 min )

Article originally published here : https://alsohelp.com/blog/how-to-display-git-shortsha-in-terminal I had a problem displaying the image here on dev.to, everywhere else, the text is fine Article below : The answer is already given in this StackOverflow answer more than 6 years ago (!) and still holds true nowadays : git rev-parse --short HEAD # 4d7b213 In Git every commit is identified by a 40-character hexadecimal string named the "Git SHA". See the commit number pointer by the arrow ? (view it in original article) Yes, that's the git short SHA. Only the first 7 digits amongst the 40. The risk of collision is small enough to identify uniquely each commit. You can define an alias, on Linux or Windows, in order to display it without to remember the whole command : alias shortsha='git rev-parse --short HEAD' (exemple from my Linux machine) Will be used like this : shortsha # 4d7b213 Neat! Sometimes, you will try some attempt to display it somewhere in the footer, in order to increase confidence about which version of the website is deployed. I like and use it, but I admit it's not very common though. That was a quick recap about the git short SHA.  ( 3 min )

Introduction In the fast-paced world of software development, every line of code counts—and so does every minute of your day. As tech teams increasingly embrace remote and hybrid models, we must clearly rethink how we communicate. Daily stand-ups, endless Zoom calls, and constant Slack notifications are no longer the productivity boosters they once seemed to be. Instead, high-performing developer teams use asynchronous (async) communication to stay aligned, reduce interruptions, and get more done. Daily stand-ups were designed to be quick, focused meetings to keep teams in sync. But in reality, they often: Happen at inconvenient times across time zones Turn into lengthy status updates Break developer flow and deep work Add unnecessary meeting fatigue According to a recent GitLab Remot…  ( 5 min )

Adding scroll-based animations to your website used to mean reaching for JavaScript — from scroll event listeners to Intersection Observers or third-party libraries like ScrollMagic or GSAP. But what if you could get the same effect with just pure CSS? Meet the modern magic of CSS: animation-timeline: view(); With this property, you can create scroll-triggered animations without a single line of JavaScript. Smooth. Performant. Declarative. ⸻ 🧠 What Is animation-timeline: view();? The animation-timeline property allows CSS animations to be driven by something other than time. When you use the special value view(), the animation is controlled by the element’s scroll position in the viewport. That means your animation will start and progress based on how far the user has scrolled…  ( 4 min )

If you’re using Cursor and keep seeing this error: “Connection failed. If the problem persists, please check your internet connection or VPN” You’re not alone. This issue tends to appear randomly—even when your internet is working just fine. It can interrupt your flow and make the experience frustratingly unstable. Cursor uses the HTTP/2 protocol to power many of its AI features, since it allows streaming responses. However, not all networks handle HTTP/2 properly. If you're on a corporate network, using a VPN, or behind a proxy like Zscaler, HTTP/2 connections might fail. As a result, Cursor may struggle to index your code or connect to its AI backend—leading to that annoying “Connection failed” message. Thankfully, there’s a simple workaround. Cursor now includes a fallback to HTTP/1.1, which is slower but much more reliable on certain networks. Here’s how to enable it: Open Cursor Settings (Cmd or Ctrl + ,) Go to VS Code Settings Search for http2 Find and check the option “Disable HTTP/2” This forces Cursor to use HTTP/1.1 instead, which should fix the connection issue and restore access to AI features. ✅ Once you do this, the error should stop showing up and things will run more smoothly.

If you're using an SSD — and let’s be honest, you probably are — you might have come across a spec labeled TBW, or Terabytes Written. But what does it actually mean for the real-world lifespan of your drive? Let’s break it down in simple terms. TBW stands for Terabytes Written, and it’s a metric that tells you how much data can be written to an SSD before the drive is likely to start wearing out. Think of it like a fuel limit — not for how long the drive will exist, but for how much write work it can handle over its lifetime. For example, if your SSD has a TBW of 600, that means you can write 600 terabytes of data to it before you start entering the "wear-out" zone, as defined by the manufacturer. Let’s do a quick, real-world calculation. Say you're a regular user writing about 100 GB per day — downloading files, installing apps, updating your system, working on projects. That’s quite a bit for a typical user, but let’s go with it. 100 GB/day = 36.5 TB/year 600 TBW / 36.5 TB/year ≈ 16 years Yes, sixteen years of daily 100GB writing. That’s how much endurance a 600TBW SSD gives you. And if you write less than that (which most people do), it’ll last even longer. You can monitor your SSD’s health and total data written using tools like: CrystalDiskInfo (Windows) smartctl from smartmontools (Linux/macOS) These tools can show you how much data has been written so far, so you can get a real-time sense of your drive’s life expectancy. TBW is an important but often misunderstood metric. SSDs don’t just suddenly die after hitting the limit, but the risk of data loss increases as the flash memory wears out. That said, for most users — even power users — modern SSDs offer years of reliable performance. So the next time you see a TBW rating, don’t panic. Unless you're stress-testing your drive daily, you're probably fine for a decade or more.  ( 3 min )

In this guide, I’ll walk you through how I set up WordPress on an Ubuntu server on Azure using Nginx and added a custom welcome page to make the site more personal. I installed the core components needed to serve WordPress: sudo apt update sudo apt install nginx php php-mysql mysql-server -y I downloaded WordPress and extracted it into /var/www/html: wget https://wordpress.org/latest.tar.gz tar -xvzf latest.tar.gz sudo mv wordpress/* /var/www/html/ I edited the Nginx default configuration to support PHP and WordPress: sudo nano /etc/nginx/sites-available/default I made sure to set the index directive like this: index index.html index.htm index.php; This ensures my custom index.html is shown before WordPress’s index.php Inside /var/www/html/, I created an index.html file: Welcome Welcome to Folashade's Core Dev Test! This is a personal test environment where WordPress is installed. Login to WordPress To apply the changes: sudo systemctl restart nginx Then I go to http:// , I see a clean, welcoming landing page. Clicking the link takes me to the full WordPress setup. This setup gives me a simple branded homepage while keeping full access to WordPress in the background.  ( 3 min )

I’m currently in my final year as a student, and I recently found myself drawn into something I never expected to enjoy: formal verification. I want to share a little story about how I got here, what I’ve been learning, and why I believe formal verification might be one of the most exciting and valuable skills in the world of smart contracts and blockchain. At first, formal methods felt intimidating. I come from a non-mathematical background, and the idea of writing "proofs" with symbols and logic felt way out of my league. But I was curious. I started asking myself: how do we really know a smart contract does exactly what it’s supposed to do? This question led me to the world of formal verification. a field where we use math and logic to prove that a piece of code behaves correctly in all…  ( 3 min )

Engineering is more than formulas, projects, or classroom lectures. While academic learning builds a foundation, real-world experience shapes your mindset, communication, and decision-making abilities. From my own journey, I’ve seen how industrial training, leadership roles, and volunteering helped me grow far beyond the textbook. When you work in a real production environment, like a garment factory, you begin to understand how things actually work on the floor. Industrial training teaches you about time management, coordination, and how teams solve problems in real-time. You observe how small improvements in workflow or communication can bring large results. This kind of learning is something no classroom can fully teach. Leadership roles in university also help in developing essential soft skills. Organizing events, managing volunteers, and communicating under pressure make you more confident and responsible. It teaches you how to plan, lead, and adapt — which are valuable qualities in both academic and professional life. Volunteering adds another layer to your development. It allows you to give back to your community while also learning empathy, teamwork, and people skills. Volunteering shows that you are proactive and socially responsible, which employers and organizations appreciate. These experiences make your resume stronger, but more importantly, they shape your personality. They prepare you for interviews, teamwork, and real challenges in your career. You learn how to think practically, solve problems, and communicate your ideas clearly — all of which are essential in today’s job market. If you are an engineering student, try to step outside your comfort zone. Look for internships, attend workshops, join a leadership program, or take part in a volunteering activity. The real world is the best teacher, and the lessons you learn there will stay with you forever. Start early, stay curious, and take every opportunity to grow.  ( 3 min )

Hey there, fellow developer! 👋 Let’s talk about something we all say we love but secretly dread: testing. You know the drill—you push code, cross your fingers, and pray the CI/CD pipeline doesn’t light up like a Christmas tree. But what if I told you testing doesn’t have to feel like a chore? In this guide, we’ll break down the three pillars of CI/CD testing—unit tests, E2E tests, and code coverage—and share practical strategies to make your pipelines faster, safer, and actually enjoyable. Let’s dive in! 1. Unit Tests: The First Line of Defense What they do: Test individual functions, classes, or modules in isolation.

We didn’t set out to build a typical database. We built something that works with the Postgres you already use, scales when you need it, and doesn’t require throwing everything out just to keep growing. This is a golden age for databases. There’s distributed systems, cloud-native options, fully managed services, and battle-tested engines like Postgres that keep getting better every year. But despite all that progress, scaling your database is still surprisingly hard. Many teams still build applications with a single-node Postgres backend. It’s how a ton of apps start, and how they stay for as long as possible. And for good reason. Postgres is rock solid, well-loved, and everywhere. It’s mature, feature-rich, and backed by an incredibly active community. But fast forward a bit, and that sin…  ( 4 min )

Yesterday, when I was at the bakery buying some snacks, I overheard a conversation between one attendant with another regarding her Android phone not downloading and installing the ChatGPT app. Curious about the subject, I decided to ask her more regarding her issue, and to talk about it. She explained her smartphone was an older model, using Android 8.0, aka Oreo, and that's probably why the chatgpt android app wasn't downloading and installing on it. We talked a while, and I pondered that while there are a lot of reasons for an app not to work on an older Android OS version, the most relevant of them are the security reasons. So I decided to list eight changes from Android 8.0 (Oreo) to Android 15 (Vanilla Ice Cream), the most impactful and relevant of each major version: Project Treble …  ( 10 min )

Hello, everybody! At Info-Polus, we see the opportunities RWA tokenization presents. Today, let's dive into it! The crypto bull market is not only driving up the large, established cryptocurrencies such as Bitcoin and Ethereum. Memecoins such as Dogecoin (DOGE), Pepe, and Shiba Inu, which have a lower market capitalization and are particularly volatile, have recently attracted great attention with impressive price rallies. By contrast, the increases in real world assets (RWA) have attracted less public attention - although many experts believe this crypto segment has excellent prospects… So what lies in RWA? As the name itself suggests, Real World Assets represent tangible and other assets existing in the “real world” (real estate, exchange-traded commodities, art objects) tokenized for use in the DeFi segment. The growing interest in tokenizing real-world assets stems from the promise of greater transparency, security, and global market reach. Let the numbers speak for themselves: the DeFi industry has boomed over the past few years, peaking at $181.22 billion in total value locked (TVL) on December 2, 2021. According to DefiLlama, RWA is steadily carving out its space in this ecosystem, with a TVL exceeding $8 billion in January 2025. Interested in what the future of RWA holds for us?

During my industrial training, I had the opportunity to explore Lean Manufacturing, a system designed to make production more efficient by eliminating waste and focusing on value creation. I learned about important tools like 5S, which stands for Sort, Set in order, Shine, Standardize, and Sustain. This method helps keep workspaces clean and organized, which is essential for safety and productivity. Another key concept I studied was Kaizen, which means continuous improvement. It emphasizes that small daily changes can lead to significant improvements over time. I also gained practical experience with Just-in-Time inventory management, which ensures materials arrive exactly when needed, reducing storage costs and avoiding overproduction. This training helped me connect the theoretical concepts learned in class with real-world production challenges. I realized that efficiency is not only about speed but also about smart use of resources and people. I saw how teamwork and communication play a vital role on the factory floor. Lean Manufacturing is not just a set of techniques; it is a culture of continuous problem solving and improvement. As an Industrial and Production Engineering graduate, I believe this mindset will guide me in all my future professional endeavors.  ( 3 min )

Oreo is a black and white male cat who spends his days judging my code from the comfort of my desk chair (which he has claimed as his throne). Like most cats, he believes he owns everything - a perfect metaphor for understanding JavaScript's various scoping mechanisms! Let's start with regular class variables and methods. Oreo's name and color are regular properties - anyone can access them. class Cat { constructor(name, color) { this.name = name; this.color = color; } meow() { console.log(`${this.name} says: Meow!`); } } const oreo = new Cat("Oreo", "Black & White"); oreo.meow(); // Oreo says: Meow! console.log(oreo.color); // Black & White - We can access and modify this property Static variables and methods belong to the class itself, not instances of the class.

Hey folks, welcome! Welcome to the first article in my new series: Why Python? Unlike C, Python is widely used—and one big reason is libraries. Python comes with many built-in libraries, and you can import even more depending on what you need. Think of a library as a toolkit that helps you do things faster and easier. A Real-Life Example: Randomness Let’s say I’m playing a card game with friends. I never know which card I’ll get next—why? Because it’s shuffled. It’s random! In Python, we can use something similar: import random as rand Just like shuffling cards gives you unpredictable results, the random library in Python helps you generate random numbers or make random choices. In real life, randomness is unpredictable. Cool, right? That’s the magic of Python! Introduction to Variables Now let’s talk about variables. Imagine a kitchen shelf with jars: In programming, think of those jars as variables. Each jar (or variable) stores something inside it—just like a variable stores data. Syntax Example: Let’s say we name our jars like this in Python: jar1 = "Sugar" Now, if we want to see what’s inside, we can do: Easy, right? That’s a wrap! In the next article, we’ll look at types of variables and best practices for naming them. Happy coding! If you found this interesting or have suggestions, feel free to comment — I’d love your feedback!  ( 3 min )

In modern React development, we strive for interactivity and precision in our components, especially when implementing behaviors that involve timing, dynamic rendering, and interaction tracking. In this article, we will dive into advanced React + TypeScript concepts using a real-world mathematical example: visualizing a quadratic function graphically with controlled updates using useEffect, useRef, and custom props. We’ll create a dynamic component that animates a parabola (y = ax² + bx + c) and allows the user to update coefficients in real time. The component will: Render points on a canvas dynamically using useRef. React to prop changes via useEffect. Maintain performance using stable references and controlled rendering. Hook/API Purpose useRef Access raw DOM nodes (canvas) use…  ( 4 min )

2901. Longest Unequal Adjacent Groups Subsequence II Difficulty: Medium Topics: Array, String, Dynamic Programming You are given a string array words, and an array groups, both arrays having length n. The hamming distance between two strings of equal length is the number of positions at which the corresponding characters are different. You need to select the longest subsequence1 from an array of indices [0, 1, ..., n - 1], such that for the subsequence denoted as [i0, i1, ..., ik-1] having length k, the following holds: For adjacent indices in the subsequence, their corresponding groups are unequal, i.e., groups[ij] != groups[ij+1], for each j where 0 < j + 1 < k. words[ij] and words[ij+1] are equal in length, and the hamming distance between them is 1, where 0 < j + 1 < k, for all indices…  ( 26 min )

It’s been a long time coming, but I’m thrilled to finally share a new developer tool that emerged from my constant need for better CSS property organisation: Old Fashioned CSS Formatter — a professional-grade Visual Studio Code extension designed to fill a very real and long-standing gap in modern front-end development. If you’ve ever used CSSComb in the past, you know how much it helped maintain order in stylesheets. However, a vacuum was left with the project, which is no longer maintained, and this new tool steps in. When CSSComb stopped receiving updates, it left a hole for many developers, including me. It had a simple job: sorting CSS properties meaningfully. But it did it well. With tools like Stylelint and Prettier becoming more prevalent, it seemed like no one focused anymore on …  ( 4 min )

This is the fourth chapter in my blog series about building a Go Testing Module from scratch. If you’re new here, I recommend checking out the previous post for some context. In this post, I’m diving into two new packages I’ve created — goldy and must. These tools tackle problems you’ve probably faced in writing tests, making your test code cleaner, more readable, and a lot more enjoyable to work with. Let me walk you through how I built these packages to solve those familiar testing headaches. goldy Package You’ve likely faced the frustration of testing a function that generates a complex, multi-line string — like a JSON response or a formatted report. Hardcoding that string in your test code turns it into a cluttered mess that’s tough to read and even harder to maintain. I’ve been ther…  ( 6 min )

This post demonstrates a TypeScript pattern I've been experimenting with for the last year or so. I've been calling this pattern "inductive type constraints", but perhaps a better name would be "smart constructors", since they have "correct by construction" semantics (here's a nice article about them). "Smart constructors" definitely sounds cooler, but "inductive types" are what they're called in other typed languages, so I went with that. Before we dig into how they work, here are a few examples of how they can be used to solve a few long-standing TypeScript issues: Exact "exact types" is the 2nd-most popular feature request of all time Exact ensures that a type does not have any extra properties (Playground) Json One of the oldest TypeScript issues (#187) (Playground) In the TypeSc…  ( 4 min )

A Python package named modinit that facilitates the rapid scaffolding of AI model training repositories with a standardized, best-practice structure. This tool is designed to save time and ensure consistency across machine learning projects. In machine learning and AI development, it's common to begin with Jupyter notebooks for experimentation and prototyping. However, as projects mature, there's a need to transition this code into a more structured, maintainable, and deployable format. This transition poses several challenges: Code Organization: Notebooks often contain a mix of data processing, model definition, training loops, and evaluation code, making it hard to modularize and reuse components.

A 'Hero' is a large banner at the top of a website's home page. As it is the first thing a visitor sees when they enter a website, it's the one chance to make a first impression. This can be an image or a video. For our purposes, we'll only need an image. This image should be high-quality and meaningful. A purely decorative image won't do. It should convey the proposition of a fall festival in some capacity. The image shouldn't be too busy either. Negative space is necessary, as the purpose of the central graphic is to complement the other components of the section, not override them. The text block is where you capture interest.

Calculus is often taught as a tool for solving problems, such as rates of change, areas under curves, and optimization. But what if it’s also a lens to understand how the world quietly evolves? In coding, every function, loop, and variable tells a story about change—about moving from one state to another, sometimes subtly, sometimes dramatically. The derivative isn’t just a slope; it’s a whisper about the next moment. The integral isn’t just an area; it’s the sum of all moments passed. As a developer and math lover, I find myself drawn to these silent narratives, where math and code meet philosophy. In this space, I’ll explore those intersections: How math powers AI models How quantum ideas challenge our intuitions How elegant code can be more than just efficient — it can be poetic. If you love thinking deeply about the things most take for granted, welcome aboard. Let’s decode change together!!  ( 3 min )

Don’t worry, In this post, we’ll break things down simply so you can understand what’s happening behind the scenes when a message is sent using UDP. Think of a UDP packet like a shipping box. It contains two things: A very small label (header) – just 8 bytes long The actual content (data) – what you want to send The label has the following four items: Source Port (16 bits): Like the return address, it tells the receiver where the message came from. Destination Port (16 bits): Tells where the message should go - kind of like a delivery address. Len…  ( 5 min )

Have you ever wondered how Node.js handles asynchronous operations so efficiently? The secret lies in the Event Loop, a core component that orchestrates the execution of tasks. In this series, "Node.js Event Loop Visualized," we will dive deep into the inner workings of the Event Loop using a powerful tool: the Event Loop Visualizer. The Event Loop Visualizer is a tool I've been developing, based on a fork of an existing project. It offers a unique insight into the real execution of the Event Loop by utilizing a modified version of the Node.js core. Unlike other tutorials, courses, and posts that often rely on simulations to explain the Event Loop, this tool captures the actual execution, recording each phase in real-time. This provides a clearer and more accurate understanding of how Node.js manages tasks and events. Feel free to explore the Event Loop Visualizer and see it in action for yourself! The Event Loop Visualizer is composed of several key sections: Code Editor: Write and execute JavaScript code to see how it interacts with the Event Loop. Macrotask and Microtask Queues: Visualize how tasks are queued and processed. Call Stack: Observe the current call stack and how functions are executed. Event Loop Phases: Track the different phases of the Event Loop, such as Timers, Poll, and Check. Ticks & Rejections Loop Phases: Understand how Node.js handles next ticks and microtasks. Metrics: Monitor loop counts and event processing statistics. Simulated Terminal: View real-time output from your code execution. In each post of this series, we will analyze a specific block of code and explore how it is executed within the Event Loop. We'll cover a range of examples, from basic like timers to more advanced such as handling sockets and streams. Stay tuned as we embark on this journey to demystify the Node.js Event Loop. Whether you're a seasoned developer or just starting, this series will provide valuable insights and practical knowledge. Let's get started!  ( 3 min )

Epic filed a new build on May 14 after Apple ignored their May 9 resubmission, even though Apple usually reviews 90% of apps within a day. A 2021 court injunction told Apple to “quit it” and follow the rules, but didn’t actually force Fortnite back on the store, so Apple’s free to leave the game hanging. Meanwhile, Sweeney’s been all over X pointing out Fortnite knock-offs that Apple approved (and some it quietly yanked), stoking fan outrage and shine a spotlight on the limbo. With zero word from Apple and a crucial update looming, iOS Fortnite players are left staring at a loading screen—and nobody knows what Epic will do next.  ( 3 min )

TL;DR: Samsung demoed a tiny 1.4-inch RGB OLED-on-Silicon panel packing a whopping 5,000 ppi—outclassing Apple’s Vision Pro (3,386 ppi) and Meta Quest 3—at SID Display Week. The microdisplay can hit 15,000 nits brightness at 120 Hz with 99% color gamut, effectively banishing the “screen door” pixel grid in VR. Beyond VR headsets, Samsung cranked a lower-density demo (4,200 ppi) to over 20,000 nits and notes the same tech could slot into a smartwatch. By building OLEDs onto silicon wafers, it uses chip-fab tricks to cram in ultra-tiny, super-bright pixels for next-gen wearables.  ( 3 min )

Max Mode in Cursor caught my attention because of how easy it is to enable—and how quietly it can start racking up costs. There’s no prompt, no permission gate, and no usage alert. It made me wonder: in an enterprise setup, how would we even know if someone turned it on? Cursor recently rolled out Max Mode, giving users access to their most powerful models—like GPT-4o and Claude Opus—with massively expanded context and smarter completions. It’s a great feature. But if you’re managing Cursor on an enterprise account, there’s a pretty big catch: anyone can turn it on, and it immediately starts billing your account. Here’s what Max Mode is, how it works, and why I think the lack of admin controls is a risky move. TL;DR: Max Mode in Cursor gives users powerful models with expanded context—but …  ( 6 min )

I got selected to move forward for a Software Engineer (Frontend) role with a foreign company from a cold DM and was given a test assignment. I delivered beyond the expected result, only to receive feedback from a review that seemed out of touch with current web development best practices, especially within the Vue 3 and Nuxt 3 ecosystem. A senior engineer who looked over my work remarked, “It’s clear you are better than the reviewer,” which inspired me to share this story. The review listed several shortcomings: No Composition API usage. No project architecture. Code repetitiveness. No cards stored in localStorage. Not following the Figma design. Bugs. Many of these points were vague or incorrect. Let’s examine each claim. Reviewer’s Claim: “No composition (Vue 3)” Reality: Every componen…  ( 5 min )

Hey Guys! This blog will make you understand what YAML is all about. Initially it was called Yet Another Markup Language, but later renamed to YAML Ain't Markup Language (a recursive acronym). YAML is the cleanest way to write configuration files. I'm guessing you already know we need config files for certain tasks while developing apps or working that DevOps magic. There are multiple ways to write configuration files such as XML, JSON, and TOML (plus several others), but YAML has some distinct advantages. These file formats make developers happy and help our data dance from server to server or client to server. They're primarily used for transmitting data between servers and clients, particularly in web applications. These are basic data formats for writing important stuff like secret fil…  ( 7 min )

Given a sorted array of numbers and a target sum, find the pair of numbers that add up to the target sum. Example: Input: [1, 2, 3, 4, 5, 6], Target: 10 Expected Output: [4, 6] (since 4 + 6 = 10) Let's explore two approaches to solve this problem: the straightforward brute force method and the more elegant two-pointer technique. The brute force approach is the most intuitive way to solve this problem. We'll check every possible pair of numbers in the array and see if they add up to the target sum. Use two nested loops to consider every possible pair For each pair, check if their sum equals the target Return the pair when found function findPairBruteForce(arr, targetSum) { for (let i = 0; i < arr.length; i++) { for (let j = i + 1; j < arr.length; j++) { if (arr[i] + arr[j] === …  ( 6 min )

Leave Script Behind (aka LSB) is a tool I developed in the past years, it was initially designed for developers, more specifically, DevOps. I have been working on it for a few years and I think it's time to publish it for others to benefit from it. Since from the invention of the Internet, more and more software are moved to the online world as services, and the developers are moved to work in the DevOps mode. Besides the coding environments, they inevitably need to work with shells and command line tools as part of their daily work, from coding work, to service deployment, live site investigation and mitigation, etc. Depends on which operating systems they are using, they may need to interact with different types of command-line shells, such as PowerShell on Windows, GNU bash on Linux, an…  ( 6 min )

By: Matt Butcher The WebAssembly System Interface (WASI) specification is a proposed standard that describes how to connect a WebAssembly application to its underlying environment. Designed with security at the fore, WASI describes mechanisms for Wasm applications to interact with system resources such as clocks, sockets, filesystems, environment variables, and other Wasm components. The original WebAssembly project was jointly created by Mozilla, Google, Microsoft, and Apple in order to provide a common language runtime inside of the web browser. Following the path of web standards like HTML and CSS, the early Wasm creators decided to standardize the technology through the W3C.

You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer.

an **Intelligent Agent **is an entity that perceives its environment, takes actions autonomously to achieve goals, and may improve its performance through machine learning or by acquiring knowledge. Leading AI textbooks define artificial intelligence as the "study and design of intelligent agents," emphasizing that goal-directed behavior is central to intelligence. A specialized subset of intelligent agents, agentic AI (also known as an AI agent or simply agent), expands this concept by proactively pursuing goals, making decisions, and taking actions over extended periods, thereby exemplifying a novel form of digital agency.[1] Intelligent agents can range from simple to highly complex. A basic thermostat or control system is considered an intelligent agent, as is a human being, or any ot…  ( 4 min )

1. Introduction As organizations increasingly migrate workloads to the cloud, cost management becomes a critical component of sustainable operations. While cloud services like AWS offer flexibility and scalability, they also come with the risk of escalating expenses if not carefully monitored. This is where FinOps — a practice that blends financial accountability with cloud engineering — plays a key role. 2. Understanding EC2 Cost Structures To effectively reduce AWS costs through automation, it's essential to first understand how EC2 (Elastic Compute Cloud) pricing works. AWS offers a flexible pricing model for EC2 instances, but this flexibility can also lead to overspending if not managed carefully. 2.1 EC2 Pricing Models On-Demand Instances: These are billed per second (with a mini…  ( 10 min )

Hey Rails devs! 👋 If you're using Active Storage in your Ruby on Rails applications (and let's be honest, it's pretty awesome for handling file uploads!), you've probably experienced its power and simplicity. But have you ever wished you could easily see what's going on under the hood? Like, a proper dashboard to visualize your blobs, attachments, and overall storage usage? I found myself wanting exactly that. Digging through the console or database to check on files, their metadata, or how much space they're consuming can be a bit tedious. That's why I built Active Storage Dashboard! Active Storage Dashboard is a mountable Rails engine that provides a sleek, modern, and (dare I say) beautiful dashboard to monitor and inspect your Active Storage data.

Ever been in a daily Scrum where developers list empty words like “I coded the UI”? That’s a status update, not a sprint goal discussion. I’ve seen this confusion tank team focus for many years - and yes, I fix it every time. Sprint goals are Scrum’s core, yet developers often treat them as empty to-do lists. So let’s explore why developers confuse them with status updates, why sprint goals matter and how to fix the status update confusion to deliver real value. Why the confusion? A sprint goal is a clear outcome, like “Our team will allow users to enable gravitational anti-matter this sprint so that users can fly above water in their cars” or “We need to reduce technical debt to free up 25% of EC2 resources for other higher value added batches.” It’s the common why for the whole team t…  ( 5 min )

How NGINX Works Web Server Acting as a Reverse Proxy: The Middleman with Superpowers Here's how it works: A client sends an HTTP request to your web application. NGINX receives the request first, acting as the front-facing gateway. Based on its configuration, NGINX forwards the request to the appropriate backend server. The backend server processes the request (e.g., querying a database or rendering a web page) and sends the response back to NGINX. NGINX then returns the response to the original client. Key Advantages of Using NGINX as a Reverse Proxy: Load Balancing: Distributes traffic across multiple backend servers using strategies such as round-robin, least connections, or IP hash. Caching: Caches responses from backend servers to improve speed and reduce load. SSL Termination: H…  ( 5 min )

In modern web or mobile development, working with dynamic URLs is common — especially when environments (development, staging, production) have different base URLs but share similar API paths.

Introduction What is a Media Query? A media query is a CSS technique used to apply styles based on the device's characteristics, like screen width, height, orientation, or resolution. It helps make websites responsive. Syntax of a Media Query @media only screen and (max-width: 600px) { @media is the rule. only screen targets screen devices. (max-width: 600px) means it will apply when the screen is 600px or less. Inside the curly braces, you write the CSS rules that should apply. Common Media Query Breakpoints /* Small devices (phones) */ @media (max-width: 600px) { ... } /* Tablets */ @media (min-width: 601px) and (max-width: 992px) { ... } /* Laptops */ @media (min-width: 993px) and (max-width: 1200px) { ... } /* Desktops */ @media (min-width: 1201px) { ... } These are just examples. You can set custom breakpoints based on your design needs. Why Media Queries Matter Improves user experience across different devices Helps build mobile-friendly websites Allows you to customize layouts for different screen sizes My Practice Example /* Default style */ /* For mobile screens */ @media (max-width: 600px) { This changes the paragraph text size and color on smaller screens.

If you don't know me yet, I have been working on ArkScript for nearly 6 years now. ArkScript is a scripting language in modern C++, running on a custom virtual machine (like Python or Lua), with the goal of having a syntax easy to learn and use, a C++ interface to embed it in programs, and decent performances (without trying to be as fast as Lua though, Mike Pall is a genius and did outstanding work on LuaJIT). A silly question that you shouldn't care about, unless the perceived slowness of the language is becoming a problem.

A large part of state management is data management - who owns data? How are limits kept track of? How is data allocated and destroyed? Our system has objects transparently migrating from server to server, so pointers are not an option - we have references instead. References can become invalid if the referenced object is destroyed, which leaves us with two options. Guarantee at the compiler and runtime level that all references remain valid while used, through lifetime tracking and the borrow checker, or force the programmer to handle the case of an invalid reference on every access. The latter is easier, if we introduce "owning references", which there can be only one of, and that are always valid. In fact, when an object is just declared as a field of another object - that's an owned re…  ( 5 min )

Git adalah salah satu sistem kontrol versi yang paling populer di dunia pengembangan perangkat lunak. Salah satu fitur yang sering kali membingungkan tetapi sangat berguna dalam Git adalah rebase. Dalam tutorial ini, kita akan mempelajari secara mendalam tentang Git rebase, cara menggunakannya dengan benar, dan praktik terbaik yang harus diikuti. Git rebase adalah perintah yang memungkinkan Anda mengubah sejarah commit dengan memindahkan, menggabungkan, atau memodifikasi rangkaian commit yang ada. Secara sederhana, rebase mengambil satu cabang dan "menempatkannya kembali" di atas cabang lainnya. Perintah git rebase memiliki fungsi yang mirip dengan git merge, keduanya dirancang untuk mengintegrasikan perubahan dari satu cabang ke cabang lainnya.

Ever wondered how JavaScript can fetch data from an API, wait for a timeout, and respond to user clicks, all without freezing your browser? It's not magic, it's the event loop. Even though JavaScript runs on a single thread, it handles multiple operations seamlessly using a clever system of background tasks, queues, and scheduling. Before we dive into how the event loop keeps things running smoothly, let’s break down the key components that make JavaScript’s async behaviour possible. Call Stack: Web APIs / Node APIs: These are provided by the browser or Node.js, things like setTimeout, fetch, DOM events, etc. They run asynchronously outside the main thread. Task Queue: After a Web API finishes (like a setTimeout), it sends the callback to the Task Queue. Microtask Queue: For things like Pr…  ( 4 min )

"Honest disagreement is often a good sign of progress." - Mahatma Gandhi. I saw that quote the other day, and it sort of lodged itself in my brain. I’m a pretty heavy YouTube consumer – it’s where I get news, learn stuff, find entertainment, the whole nine yards. And lately, watching hours of content, I’ve started to notice something… a kind of invisible wall that seems to go up around certain creators. You know how it is. You find a creator you vibe with. Their takes are fresh, or funny, or they just explain things in a way that clicks. So you subscribe, hit the bell, all that. And then you scroll down to the comments. And often, especially with more established channels, it's just… a sea of agreement. Pure affirmation. "You're so right!" "This is exactly what I was thinking!" "Best chann…  ( 5 min )

Javascript is one of the core technologies of the World Wide Web, alongside HTML and CSS.It's a high-level programming language used to add interactivity to web pages.Before JavaScript, webpages were static — they displayed content and provided hyperlinks which enabled the user to navigate through the Web, but offered little in terms of user interaction or dynamic behaviour.JavaScript changed this by enabling developers to create dynamic, responsive web experiences, allowing real-time content updates, interactive forms, and engaging user interfaces directly in the browser. Each web browser has its own JavaScript engine that interprets and executes JavaScript code, converting it into machine language to run on the computer's hardware.This javascript engine plays a pivotal role in providing …  ( 6 min )

Web apps are under siege in 2025. Cybercriminals are more sophisticated, APIs are under constant attack, and traditional authentication methods like session cookies or static API keys just don’t cut it anymore.

In 2025, we finally made the call — Sails.js is out of our stack. We tried hard to keep Sails alive. We added TypeScript, wrote custom types, wrapped controllers, hacked the models, and even considered forking it to modernize the whole thing. But the deeper we went, the more obvious it became — the foundation just isn't made for today. Outdated patterns, broken dependencies, Docker images with critical vulnerabilities... The project is barely maintained — just version bumps for security. It’s no longer a tool for modern development. Our main project today is RestoApp — an open-source platform for restaurants, food delivery, and retail. A big part of it is the admin panel. Originally, we started from sails-hook-adminpanel by Kostya Zolotaryov — and we’re genuinely thankful to him for that. It gave us a solid starting point. Over 8 years, we evolved it a lot — changed frontend stacks multiple times — and today, it’s become a fully independent, configurable, and open-source admin system. No longer tied to Sails, no specific ORM, no locked-in logic. Just a single config file — and it works. Meet Adminizer 📌 What’s next? So yeah — this is our goodbye to Sails. Now — we move forward.  ( 3 min )

We store data to record the state: A password change, an order made, an order delivered and etc. Such things can be seen as stand-alone events or, in many cases, they are part of a step in a process. And, it's common to see those things be chucked into a single table. All those columns can result in models that bloat to 1000s of lines. When looking at a model like that, you may have an urge to group all columns and methods to make sense of what is going on. It's tiring enough doing it once, but it becomes a bigger issue when you and others have to go through the same process each time. In situations like this, proxy models can become invaluable! They can enable you to split columns in models into targeted sections. In this article, I will: Share the basics of what proxy models are Why sho…  ( 5 min )

ORM technology indeed simplifies basic CRUD operations, but it also has many limitations when dealing with complex calculations. Hibernate’s HQL is notably inadequate, making it difficult to implement dynamic column calculations and multi-layer associations. While JOOQ improves flexibility through its DSL, its grouping calculations require multi-layer nesting, leading to more verbose code than native SQL. esProc SPL is like a “plug-in” for data computation! To write a multi-layer JOIN based on dynamic conditions, you had to use chain calls in Java for half an hour with JOOQ. Now you can implement this in just a few lines of SPL script, and its syntax is more intuitive than SQL. For example, calculating ‘top 3 sales by department’, which even requires nesting in SQL: SELECT dept, name FROM …  ( 5 min )

Hi! I’m Kostiantyn, a 14-year-old fullstack developer with solid skills in JavaScript and TypeScript. Over the last few months, I’ve earned more than $3,000 working on real projects and freelancing — all before even finishing high school. Mastering JavaScript/TypeScript and Next.js for fast, scalable frontend and backend development. Building simple SaaS projects that solve real problems and bring real income. Learning backend basics with Node.js and NestJS, since this stack is in huge demand. Why I Put Go on Hold I started learning Go because it’s popular for backend and microservices. But quickly realized it doesn’t fit my current goals. Go requires more time to master and lacks the quick feedback loop I get with JavaScript and Node.js. For now, I prioritize skills and tools that help me earn money faster and build complete products. To keep building SaaS products and freelance projects that improve my skills and generate income. Practical experience and fast results are key at my age. I’ll continue focusing on JavaScript, Next.js, and NestJS, then later consider other backend languages like Go or Rust when I’m ready for bigger challenges. Thanks for reading! Feel free to follow my journey and share your own experiences. Let’s grow together. Check out my SaaS project: https://charm-ai.io  ( 3 min )

Oh, look—Java decided to join the AI party! And no, it’s not just another half-baked wrapper around TensorFlow that makes you question your life choices. Meet Brain4j, a supposedly functional, open-source machine learning framework for Java developers who refuse to switch to Python like sensible people. Hold Up—Java Can Do AI Now? Yes, apparently. While the rest of the world was busy worshipping at the altar of Python and PyTorch, some brave (or stubborn) souls decided: "Hey, what if we made AI in Java without summoning Cthulhu?" And thus, Brain4j was born. "Features" (Because Every Framework Needs a Sales Pitch) Neural Networks That Don’t Require a PhD Feedforward nets? Check. CNNs and RNNs? Sure, why not.

A Nostalgic Story About 8 years ago, when I was just a kid, I began my coding journey with a school book — you know, the classic QBASIC chapter. I learned about variables, conditional statements, and control flow, writing small programs like basic calculators and whatnot. But then, there was this one section at the end... That single section changed everything. I learned how to draw rectangles, circles, and all kinds of shapes on the screen. And then my brain started buzzing with ideas. You know what’s coming next… my very first game. If you’re a tech person, you’re probably thinking: “Who the hell makes games in QBASIC?” 😅 Well… an innocent 11-year-old me did. I didn’t know how to Google things back then (heck, I barely knew what Google was). But somehow, with a school textbook and sh…  ( 4 min )

JavaScript is evolving faster than your npm dependencies can break. ESNext refers to the bleeding-edge features currently proposed or recently added to the ECMAScript spec — and if you're not keeping up, you're falling behind.

Ever recorded a great video, only to find the playback looks jittery or rough — especially during fast motion? Whether you’re editing old footage or polishing new content, one thing can instantly improve the experience: higher FPS (frames per second). Here’s why frame rate matters more than you might think, and how modern AI tools like UniFab Video Enhancer AI can help you achieve silky-smooth playback — without re-recording a single second. Why Frame Rate (FPS) Matters FPS determines how many frames appear each second in your video. More frames = smoother motion. 24 FPS – Classic cinematic feel, but can appear slightly stuttery in fast scenes 30 FPS – Standard for web video, balanced and widely supported 60 FPS and above – Ultra-smooth, ideal for sports, gaming, action, or modern so…  ( 4 min )

Description: Learn the basics of key HTML tags and how to build your very first simple webpage with easy-to-follow code examples. Introduction Figure: A historical newspaper front page (Hilo Tribune). HTML stands for HyperText Markup Language, and it’s the foundation of every web page. It uses code (tags inside ) to tell your browser how to display content. This is similar to how a newspaper uses headlines and sections to organize information. For example, the image above shows a newspaper with a big headline and columns of text. In HTML, we create structure with heading tags ( through ) and paragraph tags ( ), just like the title and stories in a newspaper. Why HTML Matters When a browser loads a website, it reads the HTML file to decide what to show. This makes HTML the s…  ( 5 min )

How Java Stores Data in Memory — Primitives vs Non-Primitives Java is a statically typed language, which means every variable’s type must be known at compile time. This allows the JVM (Java Virtual Machine) to allocate memory efficiently and enforce type safety during execution. Primitive types are the building blocks of data in Java. They have fixed memory sizes and are stored in the stack. The value of a primitive can change, but its size does not. Type Size Description byte 1 byte Smallest integer (–128 to 127) short 2 bytes Short integer int 4 bytes Default integer type long 8 bytes Large-range integer float 4 bytes Single-precision float double 8 bytes Double-precision float char 2 bytes Unicode character boolean 1 bit* True or False (handled as 1 byte internall…  ( 5 min )

🚫 Top 10 Common Mistakes in Kotlin Programming Treating nullable types as non-null without checks. ✅ Use ?., ?:, and !! carefully. Prefer safe calls and smart casting. !! (Not-null Assertion) Using !! too much can crash the app with NullPointerException. ✅ Use null-safe operators and proper null checks instead. var Instead of val Declaring variables as mutable (var) when they should be immutable (val). ✅ Prefer val for safer, more predictable code. Using apply, let, also, etc., without understanding context. ✅ Choose the right scope function for the right purpose. == and === == checks structural equality, === checks reference equality. ✅ Know when to use each depending on what you're comparing. Not using try/catch when calling risky operations (e.g., parsing, IO). ✅ Always handle exceptions gracefully. Launching coroutines without a proper scope or dispatcher. ✅ Use structured concurrency: lifecycleScope, viewModelScope, etc. Reinventing functions already available (e.g., filter, map, groupBy). ✅ Explore and master Kotlin’s powerful standard library. Not converting Java-style code to idiomatic Kotlin. ✅ Embrace Kotlin syntax, avoid Java habits (e.g., setters/getters, verbose loops). Explicitly declaring types unnecessarily. ✅ Let the compiler infer types where obvious – cleaner and shorter code. Generate exclusive photo for your post  ( 3 min )

Conceptual Comparison: Developer Mindset, Responsibility Separation, and Task Decomposition Building on the previous article, this one will explore the shift in developers' mindset when transitioning from API development to A2A development. Developer Mindset Shift: Function-Oriented vs. Agent-Oriented. Traditional development often involves thinking in terms of functions or API call sequences: starting from input, invoking services step-by-step, and finally producing output. Developers act as "orchestrators," controlling every step. In contrast, agent-oriented architecture requires a new mindset—designing a community of agents, each responsible for a subtask and interacting via messages and protocols. Instead of scripting flows directly, developers configure systems of autonomous agents,…  ( 5 min )

Understanding == vs Equal() for comparing time When working with time values in Go, one of the most common operations is comparing two timestamps. However, this seemingly simple task can lead to subtle bugs if you're not aware of the differences between using the equality operator (==) and the Equal() method. The equality operator (==) compares all fields of the time.Time struct, including the location information and the monotonic clock reading. This means two times that represent the exact same moment might not be considered equal if they were created in different ways or have different internal representations. t1 := time.Date(2023, time.January, 1, 0, 0, 0, 0, time.UTC) t2 := t1.In(time.FixedZone("UTC-8", -8*60*60)) // These times represent the same instant but have different locati…  ( 13 min )

The first phase of the project, a high-fidelity interactive prototype, is finally complete! This iteration is a sort of detailed rough draft showcasing the design and functionality of the website, mostly using placeholder content. The final straw for this iteration was the addition of the Gallery page. public/gallery/ directory. This means images can be uploaded directly into this folder, and they'll automatically appear with the next site build. To achieve this functionality, the /gallery route is rendered dynamically on the server: export const dynamic = 'force-dynamic'; Rendering the page server-side allows the use of Node's built-in fs module to directly access files on the server: const galleryDir = path.join(process.cwd(), 'public', 'gallery'); let allFiles; try { allFiles = await fs.readdir(galleryDir); } catch (e) { console.error('Could not read gallery directory:', e) allFiles = []; } // Filter to only image files (jpg, png, gif, etc.) const images = allFiles.filter((file) => /\.(jpe?g|png|gif|webp|avif)$/i.test(file) ) I'll be utilizing Statsig to implement feature flags which will allow us to hide and show seasonal Hero sections without interacting with code. Currently the Hero section says: Open soon Real Farm Fun Clearly, this Hero is only really valid until fall, when it'll have to be changed to say something like "Open Now" and link to the Visit page.

In this article, we will explore how to push data from a PHP array into multiple Joomla tables that share similar but not identical structures. If you're working with Joomla and need to insert values into different tables based on specific column mappings, this guide will provide you with step-by-step instructions. Understanding the Data Structure To start, we have an array with numerical data structured as follows: $data[1] = 1; $data[2] = 2; $data[3] = 3; This array contains three numeric values. In our case, we want to distribute these values across five different Joomla tables, but each table may only have certain columns available. Why You Need to Consider Table Structures Joomla, like many content management systems (CMS), often involves various tables that may not have identical co…  ( 4 min )

Laravel is one of the most popular PHP frameworks, and for good reason—it's elegant, expressive, and comes with many built-in security features. But just because Laravel provides the tools doesn’t mean you’re automatically safe. Whether you're building an MVP or maintaining a large-scale application, security must be a priority. Here are 15 Laravel security best practices every developer should follow in 2025: Always keep Laravel, its dependencies, and PHP up to date. Laravel releases often include security patches and improvements. Laravel's Eloquent ORM and query builder automatically use prepared statements. ✅ Safe: $users = DB::table('users')->where('email', $email)->get(); ❌ Avoid: DB::select("SELECT * FROM users WHERE email = '$email'"); Escape all output using Blade syntax: {{ $us…  ( 4 min )

As a beginner in C++, you might find yourself needing to convert strings to integers, for which you have already encountered functions like atoi and strtol. While atoi is straightforward, it lacks error checking, making strtol a more robust choice due to its ability to handle conversion errors properly. In this article, we will dive deeper into understanding *temp and &temp when using strtol, clarifying how they work and when to use each. Why Use strtol for String to Integer Conversion? The strtol function is preferred for converting strings to long integers because it provides better error handling. It allows you to detect whether the conversion was successful and if the entire string was converted. Here’s a quick overview of how to use strtol: Prototype: long strtol(const char *nptr, cha…  ( 5 min )

SQL queries are an important tool for retrieving data from databases and are widely used in the field of computer science. SQL stands for Structured Query Language, and many tools can be used to run SQL queries, such as PyCharm and Anaconda Spyder. Below are five essential SQL query concepts that everyone should know. Usage: retrieve specific types of data from a table based on filters. SELECT emp_name Note: Filters are always important, as without them, the data can be overwhelming and may include a lot of unnecessary information. Usage: It is widely used for summarizing data and can be combined with aggregate functions. SELECT department, count(*) AS emp_count Note: Aggregation is useful for identifying patterns and uncovering hidden trends in the data. Usage: Joins are used to com…  ( 4 min )

Here is a quick way to avoid nil errors and get better failures in Ruby and Ruby on Rails. Convert hashes with known keys into Structs: data = { a: 1, b: 2, c: 3} ... MyData = Struct.new(:a,:b,:c) data = MyData.new(a: 1, b: 2, c: 3) Structs will throw if you introduce a typo instead of returning nil. This tightens your feedback loops and reduces debugging time. hash[:d] => nil struct[:d] => in 'Struct#[]': no member 'd' in struct (NameError) That is cool. What about in more fluid situations like user input? You can convert arbitrary incoming hashes into known structs quickly with the following: params = {a: 1, b: 2, c: 3, x: 9, z: 0} MyData.new(**params.slice(*MyData.members)) While Structs have much the same interface as hashes, there are some tricky differences. Hash#each is equivalent to Struct#each_pair. Hash#keys is equivalent to Struct#members. There is no equivalent to Hash#fetch.  ( 3 min )

Tokenization could open new opportunities for retail investors to access traditionally restricted asset classes, according to Johann Kerbrat, senior vice president and general manager of Robinhood Crypto, who called it “very important for financial inclusion.” Speaking at the Consensus 2025 event in Toronto, Kerbrat said that some real-world assets, such as real estate and private equity, are available only to up to 10% of the US population. “You need to be an accredited investor to invest in private equity right now,” he said. “How many people can afford a house or an apartment in New York?” he elaborated. “But you can get a piece of it with fractionalization, through tokenization. And so we think it makes it a lot easier to be exchanged, a lot more accessible for everybody.” Robinhood'…

The Filecoin Foundation and Lockheed Martin Space have successfully transmitted data in space using a version of the InterPlanetary File System (IPFS) on a satellite orbiting Earth, Marta Belcher, president of the Filecoin Foundation, told Cointelegraph.  Filecoin and Lockheed Martin adapted the system for use in space and successfully tested it, Belcher said during the Consensus 2025 conference in Toronto. The IPFS enhances privacy and security compared to traditional web protocols, such as HTTP, by identifying data based on its content rather than its location. This has additional benefits for data transmission in space, Belcher said. “The architecture is well-suited to space because it reduces delays, compensates for data corruption caused by radiation, and enables cryptographic verific…

At least one partner at Sequoia Capital was reportedly impacted by the recent data breach among Coinbase users, suggesting that data from others at the venture capital firm may also have been compromised. According to a May 16 Bloomberg report, Sequoia Capital Managing Partner Roelof Botha’s personal information available through his Coinbase account was stolen after a group of cybercriminals bribed the exchange’s support agents for access to user data. Though Botha had not publicly disclosed his net worth, estimates suggested he had hundreds of millions of dollars in assets. Coinbase disclosed the data breach in a May 15 blog post, saying that some of its users had been targeted with social engineering attacks after the criminals had access to their personal account information. The company said the group attempted to extort $20 million in exchange for not disclosing the breach, which Coinbase rebuffed. Though the extent of the breach was still unknown, another Bloomberg report suggested that the same type of attacks targeted users at Kraken and Binance. Cointelegraph reached out to representatives from both exchanges but had not received any response at the time of publication. This is a developing story, and further information will be added as it becomes available.

Solv Protocol has launched a yield-bearing Bitcoin token on the Avalanche blockchain, giving institutional investors more exposure to yield opportunities backed by real-world assets, or RWAs. On May 16, the protocol unveiled SolvBTC.AVAX, a token that connects Bitcoin (BTC) to real-world assets like US Treasurys and private credit offered by BlackRock and Hamilton Lane.  The new token was developed through a seven-way partnership involving Solv, Avalanche, Balancer, Elixir, Euler, Re7 Labs, and LFJ, the company said.  Solv Protocol founder Ryan Chow said the token is a way to link Bitcoin to “real-world economic cycles” in uncorrelated assets such as US government bonds and private credit, as opposed to BTC’s typical boom-and-bust four-year cycle. The token uses a multi-protocol strategy t…

Key takeaways: The total altcoin market cap (excluding ETH) gained $126 billion in Q2, fueling speculation of an altseason. The altcoin market cap, excluding Ether (ETH), has added $126 billion in Q2, sparking enthusiasm from analysts who have been waiting for an altseason. Crypto analyst Javon Marks noted a breakout that could rival the explosive 2017 bull run.  In a recent post on X, Marks highlighted a chart comparing the TOTAL3 index (total market cap of altcoins excluding Bitcoin (BTC) and Ethereum) against the US money supply, suggesting that altcoins may be on the verge of a significant rally.  A rise in TOTAL3 against the US money supply suggests that altcoins are gaining value relative to the total liquidity in the US economy, reflecting increased investor interest and capital i…

Galaxy Digital shares began trading on the Nasdaq stock exchange May 16, completing a years-long process that CEO Mike Novogratz called unfair and infuriating, CNBC reported.

A federal judge has sentenced Eric Council Jr., one of the individuals responsible for posting a fake message announcing regulatory approval of spot Bitcoin exchange-traded funds, to 14 months in prison. Following a May 16 hearing in the US District Court for the District of Columbia, the Justice Department announced that Council would serve 14 months in prison after pleading guilty to one count of conspiracy to commit aggravated identity theft and access device fraud. He was part of a group that compromised the X account of the US Securities and Exchange Commission (SEC) in January 2024 and said the regulatory body would be approving spot Bitcoin (BTC) ETFs. Prosecutors had requested that the judge impose a two-year sentence, while Council’s lawyers asked for one year and one day. Court filings showed he earned roughly $50,000 through SIM swap attacks like the one that compromised the SEC’s X account — funds likely subject to forfeiture. This is a developing story, and further information will be added as it becomes available.

Christy Goldsmith Romero of the US Commodity Futures Trading Commission (CFTC) will step down on May 31, leaving three seats open at the financial regulator. In a May 16 announcement, Romero said her last day at the agency would be on May 31, ahead of her initial plans to leave if the Senate confirmed former commissioner Brian Quintenz as the new chair. Her departure will come just one day after Commissioner Summer Mersinger is expected to step down to join the crypto advocacy organization the Blockchain Association as CEO. “It has been a tremendous honor to conclude my 23 years of federal service at an agency with such an important mission to ensure that financial markets perform their critical role in the US and global economies,” said Romero. Romero and Mersinger’s upcoming departures would leave the CFTC with only two Senate-confirmed members: acting chair Caroline Pham and Commissioner Kristin Johnson, each taking one Republican and Democratic seat, respectively. The shakeup in leadership gives President Donald Trump the opportunity to pick two more commissioners after the Senate addresses Quintenz’s nomination. This is a developing story, and further information will be added as it becomes available.

Shares of Basel Medical Group are down around 15% after the healthcare company announced plans to buy $1 billion in Bitcoin for its corporate treasury.  On May 16, Singapore-based Basel said it was “in advanced discussions with a consortium of institutional investors and high-net-worth individuals […] to acquire a US$1 billion BTC through an innovative share-swap arrangement. The company said the benefits of its planned purchase include creating “one of the strongest balance sheets among Asia-focused healthcare providers” and providing “unmatched financial flexibility for mergers and acquisitions.” It also said the Bitcoin (BTC) treasury would help Basel “[e]stablish “a diversified asset base to weather market volatility.” But the company’s shareholders weren’t sold.

As cryptocurrency gains in popularity and price, some criminals are taking to violent measures to steal funds from high-profile crypto holders. Jameson Lopp’s GitHub repository, which logs such incidents, has recorded 22 “$5 wrench” attacks on crypto holders in 2025 alone. The moniker comes from the crude and violent methods perpetrators use to compel crypto holders to hand over their bags.  In many cases, local law enforcement can intervene before anyone is harmed and funds are lost. But there is a growing trend of increasingly violent and successful attacks, some of which have resulted in permanent harm and even death. The most recent incident in Paris, France compelled the French Ministry of the Interior to hold a meeting to address the rising trend. Here are just seven of the most high…

The moniker comes from the crude and violent methods perpetrators use to compel crypto holders to hand over their bags.  In many cases, local law enforcement can intervene before anyone is harmed and funds are lost. But there is a growing trend of increasingly violent and successful attacks, some of which have resulted in permanent harm and even death. The most recent incident in Paris, France compelled the French Ministry of the Interior to hold a meeting to address the rising trend. Here are just seven of the most high…

Ripple’s legal chief said a US court’s rejection of a proposed XRP settlement with the Securities and Exchange Commission (SEC) does not pose a threat to Ripple’s win.

Why did Fantom reinvent itself as Sonic? Fantom was one of the pioneers of the directed acyclic graph (DAG) design for distributed ledgers. It featured fast finality and transaction fees of a fraction of a cent. However, Fantom relied on the Ethereum-derived account storage model and the EVM, which led to bloated storage and slow execution times. To address these bottlenecks and implement numerous other updates, the team behind Fantom rolled out Sonic, a fully independent new blockchain network. A new report by HTX  explores Sonic's technological background, its new tokenomics model and the innovations it brings to DeFi.   Download a full version of the report for free here Sonic’s technical architecture Sonic runs on the proprietary SonicVM execution engine, which dynamically translates E…

Ethereum Merge architect Justin Drake told Cointelegraph that it would be cheaper to launch a 51% attack on Bitcoin than on Ethereum. Drake said it would be “much cheaper to 51% attack Bitcoin” and that it would cost “on the order of $10 billion.” Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect in the Merge (the full PoS transition event). His remarks echo a May 14 X post by Grant Hummer, the co-founder of Ethereum-focused marketing and product company Etherealize. In the post, Hummer said that Bitcoin “is completely screwed because of its security budget.” Hummer claimed it would cost $8 billion to run a successful 51% attack, and said a successful attack is “virtually certain” when the cost slips to $2 billion. A 51% attack occurs when a si…

Bringing student loans onchain would increase the total value locked (TVL) in decentralized finance (DeFi) by more than four times, supercharging the industry, according to Yat Siu, chairman of Animoca Brands.

Deepfake-assisted hackers are now targeting US federal and state officials by masquerading as senior US officials in the latest brazen phishing campaign to steal sensitive data.  The bad actors have been operating since April, using deepfake voice messages and text messages to masquerade as senior government officials and establish rapport with victims, the FBI said in a May 15 warning.  “If you receive a message claiming to be from a senior US official, do not assume it is authentic,” the agency said.   If US officials’ accounts are compromised, the scam could become far worse because hackers can then “target other government officials, or their associates and contacts, by using the trusted contact information they obtain,” the FBI said.  As part of these scams, the FBI says the hackers a…

US federal prosecutors are pressing ahead with their case against Tornado Cash founder Roman Storm, but will drop a small part of their indictment after the Department of Justice rolled back its crypto enforcement last month.

Deputy Attorney General Todd Blanche’s April memo said the Justice Departmen…

Global foreign exchange and payments platforms are lobbying hard against stablecoins, which stand to significantly disrupt their business models, investor Kevin O’Leary said during a keynote address at Consensus 2025. Legacy forex and payments platforms often extract large fees for servicing cross-border cash transfers and stand to lose out on revenue if regulated stablecoins become accepted as a cheaper, faster alternative, O’Leary said at the Toronto conference.  “Currency trading is a multi-trillion dollar market — and it’s old and ugly and inefficient,” O’Leary said, adding that “[ t]he biggest threat to that monopoly or oligopoly is a regulated stablecoin.”  “Once that’s approved, the multi-trillion dollar FX market becomes efficient, transparent, and inexpensive,” he said.  Kevin O’…

Coinbase chief legal officer Paul Grewal addressed some of the concerns raised by US lawmakers and industry leaders around President Donald Trump’s crypto ventures, and how they may affect related legislation.

Though Grewal said there were disputes over “substantial issues that need to be addressed” in the bill, he hinted that Trump’s involvement in the industry was a “complicating factor.”  “The discussion around the president's support for a certain memecoin or two and other efforts does add a certain level of challenge to the effort to g…

There is an ongoing race across the world for Bitcoin accumulation, according to Eric Trump, the second-eldest son of US President Donald Trump.

Sharing the stage with Asher Genoot, the CEO of Bitcoin (BTC) mining company Hut 8, Trump said Bitcoin adoption has been incredible. “I'm traveling. I'm on a plane.

Steady inflows from institutional investors and the strength of the $100,000 support point to growing confidence in Bitcoin.

Asset tokenization is set to accelerate the movement of capital across traditional markets, according to Chainlink co-founder Sergey Nazarov.

"I think that there are two sides to this equation. One is the asset, and the other one is the payment.

Bitdeer Technologies Group reported a 41% year-over-year drop in revenue to $70.1 million for the first quarter of 2025, the Bitcoin miner said on May 15.  The Singaporean company clocked an operating loss of $3.2 million for the quarter, down from a $34.1 million profit during the same period last year, its earnings release said.  However, Bitdeer reported a Q1 net income of more than $400 million, largely driven by gains on convertible notes and warrants issued to stablecoin issuer Tether in 2024. Bitdeer’s revenue declines come as miners increasingly expand beyond Bitcoin (BTC) mining and pivot toward supplying high-performance computing (HPC) for artificial intelligence applications.  “As we scale self-mining and execute on our ASIC [mining hardware] roadmap, we are also advancing plan…

Starting on May 30, FTX will send more than $5 billion to creditors “within 1 to 3 business days” through crypto firms BitGo and Kraken.  In accordance with the reorganization plan, FTX said five groups of “convenience classes” would receive between 54% and 120% distribution of assets. The repayment schedule for the next class of creditors will be “announced in due course,” and the debtors were expected to pay up to $16 billion if all claims were filed. Brea…

The slow adoption of stablecoins in Canada has some local crypto industry observers concerned that the country is falling behind. The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives” in December 2022 after the FTX debacle that shook markets and turned many lawmakers against the crypto industry. Regulating stablecoins as a security has seen few local stablecoin issuers arise, but in the United States and the European Union, softening regulations have seen significant growth in the stablecoin market. This makes Canada, observers say, less competitive with other jurisdictions.  Of particular concern is the perceived gap in peer-to-peer (P2P) payments in Canada, which stablecoins are uniquely qualified to fill.  Stablecoins globally have grown …

Coinbase has reportedly fired a group of customer support agents following their alleged involvement in social engineering attacks on users. The contracted agents were based in India. According to a May 15 Fortune interview, Coinbase's chief security officer, Philip Martin, said the company flagged customer support contractors who allowed scammers access to user data, suggesting they could be Indian nationals. The CSO’s comments came after some crypto users reeled from attempted phishing attacks using their Coinbase data, which the exchange estimated could cost them between $180 million and $400 million in remediation and reimbursement. Qiao Wang, a core contributor to Alliance DAO, said in a May 15 X post that he may have been a victim of one of these attacks. He said a scammer notified him his Coinbase account had been compromised, asked him to verify his personal information, to which the criminals likely had access through the compromised agents, and requested he withdraw all his funds to a “Coinbase self-custodial wallet.” “I called them out at the end of the call telling them they need to step up their game [...],” said Wang on X. “They told me that had made $7m that day.” Cointelegraph reached out to Martin and Coinbase for comments, but had not received responses at the time of publication. This is a developing story, and further information will be added as it becomes available.

Key takeaways: Spot Bitcoin ETF inflows dropped over 90% from $3 billion to $228 million in four weeks. While strong ETF inflows often drive Bitcoin rallies, recent data shows price movements can occur independently. Despite short-term selling pressure, long-term BTC whale buying suggests a potential continuation of the BTC uptrend. The Bitcoin (BTC) market posted a 90+% drop in spot BTC exchange-traded fund (ETF) inflows, falling from $3 billion in the last week of April to just $228 million this week.

Opinion by: Jennifer Dodgson, co-founder of KIP Protocol and Eigenform AI The puppet show is ending. The Brookings Institution found that generative artificial intelligence may disrupt at least 50% of tasks performed by more than 30% of all workers.

Understanding the 10-year Treasury yield: Definition and importance The 10-year Treasury yield is the interest rate that the US government pays to borrow money for 10 years. When the government needs cash, it issues bonds called Treasury notes, and the 10-year note is one of the most watched. The “yield” is the annual return you’d get if you bought that bond and held it until it matures. It’s expressed as a percentage, like 4% or 5%. Think of it as the government saying, “Hey, lend me $1,000, and I’ll pay you back in 10 years with some interest.” That interest rate and the yield move up or down based on demand for the bonds, inflation expectations and the overall economy. Because US Treasurys are considered safe (the government isn’t likely to def…

Key takeaways: Bitcoin’s price is retracing, but strong ETF inflows, high network activity and whale accumulation suggest BTC is on track to $140,000. Spot Bitcoin ETFs saw $2.9 billion in net inflows in two weeks, mirroring past rallies. Declining exchange balances and a rising transaction volume Z-score suggest increasing overall demand. Bitcoin (BTC) price was down 1.4% over the last 24 hours. It traded 6% below its all-time high of $109,000, reached on Jan. 20.

Key points: US treasuries and foreign capital “repatriation” make a recipe for $1 million BTC, says Arthur Hayes. Europeans face tightening capital controls, inviting a recommendation to take back control of personal funds. Seven-figure BTC price targets are already gaining traction.

Chanos argued that Strategy is selling the idea of buying Bitcoin (BTC) in a corporate structure, and that other companies are following suit in hopes of receiving a similar market premium. Chanos said this was “ridiculous.” He described his trade as “a good barometer of not only just the arbitrage itself, but I think of reta…

Cryptocurrencies and stablecoins are gaining recognition in the traditional finance (TradFi) space for their ability to streamline payments and increase efficiency in existing financial systems In finance, collateral management refers to the process of managing the underlying collateral securing other financial transactions, such as loans or derivatives, to mitigate credit risks and ensure smooth transactions. Digital assets like stablecoins are the “perfect” financial instrument for real-time collateral management, according to a recent pilot by DTCC Digital Assets, which suggests that digital assets, particularly stablecoins, could modernize and simplify this critical function. “Digital assets really are the perfect use case for collateral management, whether it be uncleared derivatives,…

Coinbase, the world’s third-largest cryptocurrency exchange, was hit by a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data, the company said. According to a May 15 blog post, Coinbase said a group of external actors bribed and coordinated with several customer support contractors to access internal systems and steal limited user account data. “These insiders abused their access to customer support systems to steal the account data for a small subset of customers,” Coinbase said, adding that no passwords, private keys, funds or Coinbase Prime accounts were affected. Less than 1% of Coinbase’s monthly transacting users’ data was affected by the attack, the company said. Source: Coinbase After stealing the data, the attackers attempted to …

Private credit marketplace Pareto has introduced a new synthetic dollar aimed at linking institutional investors with decentralized finance (DeFi) opportunities — a move that highlights the expanding role of stablecoins in global finance. The newly launched USP synthetic dollar is fully backed by real-world private credit, Pareto told Cointelegraph on May 15. To mint USP, users must deposit stablecoins such as USDC (USDC) and USDt (USDT), which are then held as collateral. “USP is backed 1:1 by the stablecoins used during the minting process,” Pareto co-founder Matteo Pandolfi told Cointelegraph in a written statement. The deposited funds are placed into Pareto’s credit vaults and lent to what the company describes as “vetted institutional borrowers,” generating yields for participants. To…

Ukraine is reportedly moving closer to adopting Bitcoin as a national reserve asset, a move that could bolster its financial resilience amid the ongoing war with Russia. Lawmakers are reportedly working on a Bitcoin (BTC) national reserve proposal, with a draft bill in its final stages, according to Yaroslav Zhelezniak, a member of parliament who confirmed the plan to local media outlet Incrypted. The proposal was announced during the CRYPTO 2025 conference in Kyiv on Feb. 6. “We will soon submit a draft law from the industry allowing the creation of crypto reserves,” Zhelezniak said. Cointelegraph reached out to Zhelezniak for comment on the bill’s status but had not received a response by publication.

What is HTTP 402, and why does it matter? The web was not really built with payments in mind, especially not for autonomous agents or machines.

Opinion by: Yat Siu, executive chairman and co-founder, Animoca Brands A discussion on digital property rights, copyright, intellectual property, the open metaverse, AI and value without physical form. When I attend conferences and similar public events, someone almost always approaches me to ask how cryptographic tokens (fungible or non-fungible) can have value even though tokens are virtual and do not exist in the physical world. It's a surprisingly common question, especially one-on-one. Virtual objects like NFTs and cryptocurrencies are both digital and intangible; their existence is not based in the real (physical) world, and (unlike digital currencies) they generally do not have backing by real-world institutions.  The ability to have value (specifically, monetary worth) is crucially…

Key points: Bitcoin has a fight for both $100,000 and a $2 trillion market cap on its hands this month. Dips below six figures are “easily possible,” analyst Filbfilb says, but the odds are stacked in bulls’ favor. ETH/BTC needs to hit the 0.03 inflection point as part of an altcoin comeback. Bitcoin (BTC) is poised for expansion with BTC price action rarely more “bullish-looking,” a popular analyst says. In his latest commentary on X, popular market analyst Filbfilb revealed a key support battle now underway on BTC/USD. Filbfilb on $100,000 battle: “This time is no different” Bitcoin has begun to consolidate after making rapid gains this month, with the area just north of $100,000 seeing “choppy” BTC price moves.

Several investors of a non-fungible token (NFT) project, Hashling NFT, have accused its founder of misappropriating millions of dollars in profits from the project and a closely tied Bitcoin mining operation. According to the May 14 court filing in Illinois, the plaintiffs allege that their former business partner, Jonathan Mills, lied about transferring assets from Hashling NFT and at least $3 million from the Bitcoin mining project to a holding company — Satoshi Labs LLC (formerly known as Proof of Work Labs LLC), which Mills is the founder and CEO of. The plaintiffs have sued Mills for fraud and breach of fiduciary duty, claiming that they have not received any of the equity returns that he supposedly promised.  They also claim to have raised a combined $1.46 million from two NFT drops …

A Singapore High Court has ruled in favor of Sonic Labs’ motion to force the Multichain Foundation to wind up in an effort to recover funds stolen during a 2023 hack. In the May 9 judgment in the Singapore Supreme Court, Justice Kwek Mean Luck granted a request from Sonic Labs, formerly the Fantom Foundation, to declare Multichain bankrupt and appoint liquidators from global audit, tax and advisory service KPMG. Sonic Labs CEO Michael Kong said in a May 14 statement to X that the team behind the layer 1 Sonic blockchain felt it had no choice but to file a lawsuit to forcibly wind up Multichain because its former employees were being “completely uncooperative” and “hid from victims.” “Going forward, the liquidators can now start working with other parties to initiate the process of trying t…

The US Senate could pass a key bipartisan stablecoin bill as soon as next week after removing language targeting President Donald Trump and his family’s sprawling crypto interests. Republican Senator Cynthia Lummis said onstage at an event by Coinbase’s lobbying arm, Stand With Crypto, that she thinks it's a “fair target” to have the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed by May 26 — Memorial Day in the US. Joining her onstage was Democratic Senator Kirsten Gillibrand, who hinted that the bill’s language was changed to scrap provisions that targeted Trump’s various crypto projects, which include memecoins, a crypto platform, a stablecoin and a crypto mining company that plans to go public, among others. “When this language comes out, peop…

A major Chinese darknet marketplace suspected of facilitating crypto scams and cybercrime has been shut down by the Telegram messaging service, upon which it operated.

Some criminal organizations are yet to receive the memo — crypto is traceable — and could explain the recent string of crypto-related kidnappings, says Chainalysis CEO Jonathan Levin.  Law enforcement has been increasingly successful at tracing stolen funds and crypto ransom payments, resulting in a “lot of arrests,” Levin said during the 2025 Consensus crypto conference, covered by Cointelegraph. “For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” he said.  “Apparently, the know that crypto is not untraceable hasn't been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, b…

Coinbase CEO Brian Armstrong says his firm will continue to look for merger and acquisition opportunities after acquiring crypto derivatives platform Deribit. “We are always looking at M&A opportunities,” said Armstrong on Bloomberg Television on May 14. He added that the firm has a large balance sheet that can be put to use. The firm revealed in its latest revenue report that its balance sheet has strengthened, ending the first quarter with $9.9 billion in US dollar resources. “Part of the benefit of being a public company is, you have a liquid currency to do that,” he said, adding: “We are looking at acquisition opportunities; doesn’t mean we swing at every pitch.

European law enforcement in January arrested 17 suspects of a “mafia crypto bank” who are said to have laundered over 21 million euros ($23.5 million) in crypto for criminal entities in China and the Middle East. The money laundering services were allegedly carried out on behalf of other criminal networks engaged in migrant smuggling and drug trafficking, Europol said in a May 14 statement. Spanish authorities said the criminal organization ran a secret informal money transfer system called hawala and was often compensated in crypto. A total of 17 individuals were arrested — 15 in Spain, one in Austria and one in Belgium — while 4.5 million euros ($5 million) worth of items were seized, including cash, crypto, 18 vehicles, four shotguns and several electronic devices.

So that makes it very hard for us to make a return for our liquidity providers,” Tapeiro said while speaking in a panel discussion at the Consensus conference in Toronto on May 14. “So a lot of those deals we just pass almost automatically, even businesses that we really like, we won't invest in if the price isn't reasonable in the beginning.” 10T Holdings has passed on over 200 companies for similar reasons, including the now-bankrupt FTX, BlockFi and Celsius, Tapeiro sai…

Key takeaways: Google search data and app rankings show retail Bitcoin investor demand near 6-month lows. Retail investor interest typically peaks 1 week after BTC breaks all-time highs. Bitcoin (BTC) retail traders are known for entering the market during periods of euphoria, typically after strong monthly gains or a new all-time high. This time is no different, with Bitcoin approaching $104,000 on May 14 while general public interest and retail activity continue to lag. Analysts estimate that in 2025, retail investors were the largest net sellers of BTC, while institutions were the main buyers. But if historical patterns hold, a surge in retail appetite is likely to occur about one week after Bitcoin surpasses the $109,350 mark. Source: X/River According to River’s estimates, individu…

Introduction In Java programming, ensuring the integrity of data being inserted into a database is crucial. If your database is set to utf8 encoding, it limits you to characters within the Basic Multilingual Plane (BMP), specifically from U+0000 to U+FFFF. This means that characters beyond this range, such as emoticons and certain rare characters, will not be supported. To maintain this limit without switching to utf8mb4, it’s essential to validate the input data on the backend. In this article, we'll explore effective methods to perform this validation using regular expressions and Java code examples. Why BMP Character Encoding Matters The BMP is the first plane of Unicode, containing the most commonly used characters in modern languages, music notations, and some symbols. Using the utf8 …  ( 5 min )

Introduction You can use this article as a cheat sheet or a starting point to mastering the CLI. The CLI is one of the most essential tools in a software engineer's toolbox. As useful as it is, it can feel a little intimidating for many developers (especially on the very first encounter). Others get excited. I remember seeing the terminal for the first time and thinking, "whoa, that looks super cool, I want to master it. NOW!" But the CLI wasn't built to impress or scare anyone (especially not scare). It was designed to make our lives easier by providing the simplest form of interface possible. As developers, we should always strive for simplicity—our job is already hard enough without adding layers of unnecessary complexity. The CLI isn't only about simplicity—it's the universal tool. Y…  ( 7 min )

Understanding the Issue The problem of an Android device not appearing in IntelliJ IDEA while being visible in the command line is often due to a configuration or compatibility issue within the IDE or the device's connection settings. The fact that running flutter devices detects your device suggests that ADB is functioning correctly, and your device is connected. However, integ…  ( 5 min )

Many projects start out happily on Auth0’s free tier (up to ~7,000 MAUs), but the jump to the paid Basic plan—\$525/month for 7.5K active users—can sting fast. Beyond raw cost, teams worry about unpredictable bills, feature lock-ins, and vendor dependence. Cloud-Provider Auth Services AWS Cognito, Azure B2C, Google Identity Platform Virtually free until very high volumes, but may lack out-of-the-box UI customization. Backend-as-a-Service (BaaS) Firebase Auth (free up to 50K users/month) Supabase Auth PocketBase (self-hosted) SSOJet, Clerk.dev, Stytch, Kinde All offer generous free tiers and modern SDKs Self-Hosted Open-Source Keycloak, Ory Kratos, Supertokens, Authgear Full control and zero license fees, at the cost of hosting and maintenance overhead. Build-Your-Own Roll your own JWT-based login (e.g., using Passport.js or a simple email/password flow) Simplest for very small scale but requires ongoing security diligence. Scale & Budget: Calculate total cost at your expected growth, not just free-tier limits. Feature Requirements: Do you need MFA, SSO/SAML, social logins, or multi-tenant support? Maintenance Overhead: Self-hosting shifts burden to your team; hosted solutions offload ops at a price. Vendor Lock-In: Check data export and migration paths—some providers don’t let you export password hashes. Community & Support: A vibrant open-source community (Keycloak, Ory) or strong commercial SLAs (SSOJet, Clerk, Stytch) can save you headaches down the road. By weighing cost, complexity, and required features, you can pick a path that fits both your technical needs and your wallet—whether that’s a serverless BaaS, a self-hosted IAM, or even a custom-built solution.

Solana stands out in the blockchain world for its blazing speed and throughput. But to truly unlock that power, developers need to rethink how they build smart contracts. This guide breaks down how to write high-performance, scalable smart contracts tailored for Solana’s unique architecture. Unlike Ethereum’s EVM model, Solana is account-based and parallelizable. Programs (smart contracts) are stateless and immutable. Accounts store the state, data, and are passed into programs explicitly. The runtime can process many transactions simultaneously—if they don’t touch the same accounts. ➡️ Implication: Avoid account contention to benefit from true parallel execution. Rust: The primary language for writing Solana programs. Offers performance, safety, and tight control. Anchor: A Rust-based fra…  ( 4 min )

When working with modern C++ standards in MSVC, developers often encounter unexpected behavior when storing pointers to virtual methods in static inline variables, especially concerning issues with function calls and object lifetimes. In this article, we’ll dig into the reasons behind this behavior, particularly in the context of the provided code snippet, and explore solutions and best practices to avoid pitfalls. Understanding the Issue The issue arises from an ABI limitation related to how MSVC handles virtual methods stored in static inline variables. When you attempt to store a pointer to a virtual function in a static inline variable, MSVC incorrectly resolves the function pointer in some instances, subsequently leading to calls to the wrong function or, in some cases, even the destr…  ( 4 min )

I saw an Object Mapper component is added to Symfony 7.3. Run composer require symfony/object-mapper symfony/property-access to get the needed dependencies. For the people who don't know how Eloquent models work internally. Instead of properties a model class uses an attributes array to identify the fields. I assumed that a custom class that extends PropertyAccessorInterface would be sufficient, because I saw this code in the ObjectMapper class; $this->propertyAccessor ? $this->propertyAccessor->setValue($mappedTarget, $property, $value) : ($mappedTarget->{$property} = $value); So I created the class use Illuminate\Database\Eloquent\Model; use Symfony\Component\PropertyAccess\PropertyAccessorInterface; use Symfony\Component\PropertyAccess\PropertyPathInterface; class ModelPropertyAccess…  ( 5 min )

An AI name generator works by using algorithms—often powered by machine learning or natural language processing (NLP)—to create names that meet specific criteria or patterns. Here’s a breakdown of how they typically function: 🔧 1. Input Parameters Type of name (fantasy, sci-fi, business, product, etc.) Gender (for character names) Language or cultural origin Length or syllables Desired traits (e.g., futuristic, elegant, tough) 🧠 2. Model or Algorithm Rule-Based Systems Good for simple, consistent naming schemes. Limited creativity or adaptability. Markov Chains E.g., if trained on Elvish names, it will produce similar-sounding results. Neural Networks / Language Models Understand phonetics, style, and semantic nuances. Capable of generating unique and creative names that still "fit" a theme. Examples: GPT (like me), LSTMs, or transformer-based models. 🧾 3. Filtering and Validation Check for offensive or inappropriate content Filter by length, pronounceability, or domain availability (for businesses) Remove duplicates or overly similar results 🎨 4. Post-Processing Capitalized or stylized Modified for branding (e.g., removing vowels, adding suffixes like "-ify" or "-ly") Example: Take a dataset of known elf names (e.g., from Tolkien or D&D) Learn common phonemes or structures (e.g., soft consonants, vowel-heavy syllables) Generate something like "Elarion" or "Thalindra" Some of the example of toosls are: Elden Ring Name Generator , Tiefling Name Generator , Khajiit Name Generator  ( 3 min )

First of all, what is it like to have tinnitus? I would say, in short, it sucks. It’s a piece of quality of life that has been lost and you never experience absolute silence again. Can you live with it? Yes! Can you work as a software developer with it? Yes, of course! But it has to be said, a constant, persistent beep is a distraction, especially when a deep focus on a task is needed. I would like to make a few points about how I deal with this, especially when developing software. The first (perhaps most important for me) step in dealing with this was acceptance. In the beginning I felt shame, anger and even fear. However, with the acceptance of this new fact, it got better and my head was clearer again. I looked for nice, relaxing sounds and played them in the background. The beeping is always there, so why not cover it up with something beautiful that you like and brings you joy, I thought to myself. There are countless playlists for all kinds of sounds on the streaming platforms, such as nature and night rain. I take regular breaks and rest my body and mind during this time. In my opinion, a working day, however stressful it may be, should have at least one longer lunch break with fresh air (I’m still working on this). Nevertheless, the lunch break is an integral part of every situation where I don’t think about work for 30 minutes and recharge my batteries. I have already set up my workstation ergonomically. Of course, there’s always room for more. A desk that can be raised and lowered is a great thing. Correct posture is extremely important. I’m still at the beginning in this area and am always looking at where I can improve. Ok ok I know, admittedly sounds, pauses and ergonomics aren’t big new pro tips. I would rather like to say that this impairment loses its power when you exhaust all other possibilities and start optimizing. You should concentrate on the things you can influence and make the best of them!  ( 4 min )

In cache design, we often encounter a troublesome problem: a large number of “invalid queries” put tremendous pressure on the database. For example, when a user requests data that doesn’t exist, we typically query the database, which returns “not found.” If there are many such requests, the database gets busy handling these meaningless queries, affecting system performance. So, is there a way to know in advance whether data “might exist” before querying? This is where Bloom filters come into play. Imagine the following scenario: Our system has a cache layer (Redis) and a database layer (MySQL). When a user requests some data, we first check the cache. If it’s a cache hit, we return the result directly. If the data isn’t in the cache, we query the database. If the database doesn’t have it e…  ( 7 min )

Here's some few developer tools I've used quite a lot these past few months that has made my workflow way more fast & smooth. Most people choose the git cli over GitHub Desktop. TUI (Terminal UI), so you can easily add changes, make commits, deal with branches, revert & rollbacks, etc. And if you have a server running Git (server with TTY - no GUI), you can easily set lazygit up and use it on the go. Checkout lazygit github for some more idea Similar to lazygit, a TUI manager for docker. After using VScode for years now, I tried using Neovim. If you've heard about Vim, it is notorious for being overly complicated for no reason. write, quit, copy, paste. macros. If you wanna test out vim, would recommend Vim Tutor tool While this is not technically a developer tool, anybody can use it. After jumping from one note to google docs to Notion, I settled into obsidian. Its free, has amazing plugin support, and you get this graph of all the notes you have, that's really cool to watch. Tmux is a "Terminal Multiplexer", so suppose you have ssh-ed into a machine, and want to run two foreground process. How do you do that, both in the same terminal? pseudo terminal". That's just one example. Then switch between these terminals with keybindings, which you can customize.

AxonJs aims to provide a more structured, performant, and developer-friendly approach to building backend applications. While Express.js has been a staple in the Node.js ecosystem, it often requires additional libraries and boilerplate code to achieve a well-structured application. AxonJs addresses these challenges by offering: Built-in Structure: Encourages a modular architecture with clear separation of concerns. Enhanced Performance: Benchmarks indicate that AxonJs is up to twice as …  ( 4 min )

❌ Top 10 Common Mistakes in Writing Scripts Using fixed paths, IPs, or credentials inside the script. ✅ Use variables or config files instead. Assuming user input or arguments are always correct. ✅ Always check for type, format, and range. Ignoring exceptions or command failures. ✅ Use try/catch, if [ $? -ne 0 ], or similar. Leaving behind unused logs, temp data, or cache. ✅ Add cleanup functions or use trap in shell scripts. Continuing the script even when a step fails. ✅ Always check exit codes before moving forward. Using vague variable or function names (x, temp, data1). ✅ Use descriptive and consistent naming. Forgetting loop conditions or exit criteria. ✅ Always define clear limits and break conditions. No comments, no usage instructions. ✅ Add inline comments and a help section (--help flag). Writing credentials directly in the code. ✅ Use environment variables or secure vaults. Running scripts directly in production without testing. ✅ Always test in a sandbox or staging environment first.  ( 3 min )

Introduction If you're building an app in Android Studio and facing the error message, 'Unresolved reference: Offset', you're not alone. This issue commonly occurs when using the Relay plugin to import designs from Figma, and it can be quite frustrating. The IDE (Integrated Development Environment) may suggest an import for androidx.compose.ui.geometry.offset, but this file seems to regenerate with each build, leading to confusion. This piece aims to elucidate why this occurs and how to effectively resolve the problem. Why You Encounter This Issue The 'Unresolved reference: Offset' error typically indicates that the compiler cannot locate the class or library you are trying to utilize. In Kotlin, particularly when dealing with Jetpack Compose, the Offset class is part of the androidx.compo…  ( 5 min )

The Vaudeville era, a golden age of variety entertainment, holds a special place in the history of American theater and popular culture. Spanning from the late 19th century to the early 20th century, Vaudeville shows combined music, comedy, magic, and acrobatics in an energetic, fast-paced format. These variety performances were integral to the entertainment landscape, influencing modern-day television, theater, and even stand-up comedy. Today, the Vaudeville tradition lives on through the legacy of performers and acts that defined a unique era in the performing arts. Vaudeville was a theatrical variety show that became immensely popular in the United States during the late 1800s and early 1900s. It featured a wide range of acts, from singers and dancers to comedians, magicians, ventriloqu…  ( 6 min )

When I first encountered the term “Service Principal”, I was completely confused. If you’re getting started with cloud infrastructure, especially in Azure, the concept of a Service Principal can feel vague and overly abstract. You’re not alone — many professionals, especially those coming from traditional development or sysadmin backgrounds, struggle to understand: What exactly is a Service Principal? When and why should you use one? In this post, I’ll break it down in plain language, using real-world example and code snippets— so by the end, you’ll never be confused by the term again. Service Principal is like a user account for apps or services that need to access Azure resources. For example in order to login in the system user need user name and password, similarly its kind of user nam…  ( 4 min )

🐳Docker Basics: Containerizing Your First Web App Ever had a web app work perfectly on your laptop but completely break on someone else’s machine? Welcome to the infamous "it works on my machine" problem. Docker helps you solve that — by letting you package your app, dependencies, and environment into a portable container. In this blog, I’ll walk you through how I containerized a simple Flask web app, step-by-step. What is Docker and Why Should You Care? Docker is a tool that makes it easy to create, deploy, and run applications by using containers. A container bundles everything your app needs to run — code, libraries, and settings — into one neat unit. This means it will behave exactly the same on any machine that supports Docker. If you're a student or grad getting into development, De…  ( 4 min )

In Angular development, creating custom form components is a powerful way to encapsulate logic and maintain reusable UI elements. However, when integrating these components into Angular’s form ecosystem, many developers ask: ControlValueAccessor , or is *FormGroupDirective * more appropriate for this use case? ✅ Use ControlValueAccessor for Single Form Control Components If your custom component represents a single form control — such as an input field, toggle switch, dropdown, or similar —the correct and most idiomatic approach is to implement the *ControlValueAccessor * interface. You're building a custom input with a prefix and suffix icon: Since this component only handles a single value, ControlValueAccessor is the ideal…  ( 4 min )

Introduction The focus of this article is to run multiple services on a single port, such as hosting two websites on port 80 and port 443. As we all know from the facts that in a system there are total 65536 ports that is from 0 - 65535 ports that are being used, out of this many are system reserved ports and only small amount of ports are available on which we can expose services. Such as port 80 for HTTP, 443 for HTTPS, 22 for SSH , 3389 for RDP and so on. By default every system has at least 2 network cards, one is the loopback or the localhost network card (127.0.0.1), and another one would be either WiFi or the LAN network card (192.168.1.1). This can be checked using the command ipconfig if you are using the windows system or if you are Debian/Ubuntu distribution use ifconfig. I h…  ( 4 min )

Hey dev.to community! I was recently learning a few SecOps topics and was trying things out with the tool StackStorm (it's basically a ITTT tool for devops) that helps in event-driven automation. So then I thought of why not combine it with the good old Suricata tool and hence this blog... ;) We’ll wire up Suricata (our network IDS) to StackStorm (our event-driven automation engine), so that whenever Suricata spots suspicious traffic, StackStorm picks it up and shoots an alert into Slack. No more manually tailing logs, your chat app becomes your security ops dashboard! So enough talking and let's start doing! Coz I find it. 😂 jk. Yeah even I had this question earlier but later after gpting and trying things out, this seemed way cooler just like a security admin or smth lol. Imo, these ar…  ( 5 min )

Introduction When backloading data from a SQL Server table into a DB2 table, you might encounter errors related to null date columns. A common issue is the error message: "Operand type clash: int is incompatible with date". This happens when the data types between the source and destination databases don’t align properly, especially for nullable date columns like ACTUAL_CLOSED. In this article, we'll explore the reasons for this issue and provide effective solutions. Understanding the Issue Why Does the Operand Type Clash Occur? The operand type clash error occurs because SQL Server treats a null date value in certain contexts as an integer zero (0). When this zero gets transferred to DB2, it creates a type inconsistency since DB2 expects an actual date value, not an integer. The use of te…  ( 5 min )

Ever pushed an API key to production? Don’t lie—we’ve all done it. Here’s how to make sure it never happens again, using a 10-line Vite plugin. Secrets don’t belong in your codebase. Not in a commit, not in a PR, and definitely not in production. And yet, it happens—a quick console.log() with an API key, a test token dropped into a config file, a placeholder password that never gets removed. Days later? Still there. Weeks? Maybe it even gets pushed to production. I've heard more than one story of dev teams scanning older, inherited codebases—only to find hardcoded API keys sitting in plain text. These weren’t new mistakes, they’d been buried for years. It’s a reminder that even quiet, untouched code can hide serious risks.

Introduction As someone with nearly twenty years of experience, I've helped teams understand how their systems perform under pressure. I can tell you this: most load tests don’t fail because there aren’t enough users. And one of the biggest blind spots? Compatibility. You can run a well-designed test, simulate 10,000 users, and hit all your APIs. But you might still miss that your front-end has issues on Safari. Or, your mobile users can’t finish the checkout process. This isn’t just about performance. It’s also a compatibility problem. When you add more users, this issue becomes a performance problem. In the early days of testing, compatibility was about making sure your layout didn’t break in Netscape. As applications changed to single-page apps, mobile-first designs, and multi-device…  ( 6 min )

Basically there are 3 types: Basic Authentication, Bearer Authentication and Cookie Authentication. I will give a super brief explanation of them which can serve as a quick-remembering-guide for example. Besides that, I mention some connected topics to keep in mind without going into more detail and I have a quick code snippet as well. The simplest and oldest type - but it's insecure. So do not use it, just know about it. It's been in HTTP since version 1 and simply includes the credentials in the request: Authorization: Basic As you see, we set the HTTP header Authorization to the string username:password, encode it with base64 and prefix Basic. The server then decodes the value, that is, remove Basic and decode base64, and then checks if the credentials are c…  ( 5 min )

Kitty - A secure, encryption-focused configuration management tool written in Rust I built Kitty to solve a problem I faced while managing configuration files across servers: I wanted Git-like tracking for system config files, but with built-in encryption and the ability to keep files in their original locations. What is Kitty? Secure configuration management tool with Git-like commands Files remain in their original locations (no need to symlink like with dotfiles managers) All stored content is encrypted with ChaCha20-Poly1305 Password-protected repository access Choose between file-based or SQLite storage Works with system files that might require elevated privileges Core features: Track, version, and restore configuration files See differences between tracked and current versions Filter and group tracked files Restore previous versions when needed Privilege handling for system files Kitty is designed for sysadmins, DevOps engineers, and anyone who wants to securely track configuration files without moving them into a Git repository. The project is open source and written in Rust. It focuses on security first, with all sensitive content encrypted, making it suitable for tracking credentials and other sensitive configurations. GitHub repo: https://github.com/kometen/kitty I'd love feedback from the HN community, especially on the security model and additional features that would be useful for your configuration management workflow.  ( 3 min )

Note: I am primarily using this as a study tool as I'm upskilling my foundational knowledge. With this in mind, this document is ongoing, and I'll likely be updating it weekly. Opening and closing tags: Note: omitting the closing tag at the end of a file can be beneficial so you don't have any unwanted white space at the end of the file Printing: echo 'This prints to the screen.'; Commenting: One line: # This is a one-line comment in PHP Multi-line: /* This is a multi- line comment in PHP */ Checking variable type: var_dump($var_name); Comparing Floats: Note: Comparing floats in PHP is tricky because of precision. The following is a workaround for that limitation. String Definitions: 'this is a string' "this is a string" or echo 'this line prints a {$var}'; String concatenation uses a . rather than a + in PHP. I used PHP's documentation as the source of my information here. Some of the code will be similar or identical.  ( 3 min )

Logs are your primary tool for understanding what your API is doing in production. But many developers fall into two extremes: Too little logging, and you're blind in production. Too much logging, and you're drowning in noise, cost, or leaked sensitive data.

Laura Kankaala, Head of Threat Intelligence, F-Secure Cyber criminals have made scamming a trillion-dollar business. As technology and the internet evolve, so do scams, making them the biggest threat consumers face every time they go online or use their phone. While organizations have been trying to keep up with scammers by employing different types of cybersecurity approaches and frameworks, that same focus has been missing in consumer cybersecurity - until now. The cybersecurity industry often focuses on specific instances of scams, like someone pretending to be Brad Pitt on a dating app, or a user accidentally clicking on a malicious social media ad. We also seem to focus a lot on the psychological aspects of a scam, like certain manipulation tricks that are employed. But putting too mu…  ( 5 min )

Your website takes 8 seconds to load. In those 8 seconds, half your visitors just left. They're now on your competitor's site, credit card in hand.

Understanding AES-GCM Nonces. A Go Security Deep Dive. Once, while working on a project to upskill a bit, I came across countless resources recommending GCM (Galois/Counter Mode) for encrypting data in Go.

Your OpenAPI spec is the contract that defines how consumers interact with your API. It powers visual tools that help developers understand, test, and integrate with your endpoints. This spec powers visual tools that help developers understand, test, and integrate with your API.

I've learned it the hard way... If you use the recently released Grok-3 Mini reasoning model (which is great by the way) you might have your token usage reported wrong... While both OpenAI and xAI report reasoning usage in usage.completion_tokens_details.reasoning_tokens field: OpenAI includes reasoning tokens in usage.completion_tokens xAI doesn't include Hence for OpenAI (and according to my tests for Deepseek R1) in order to get the total tokens you can use the old good completion_tokens field. With xAI you need to add up the 2 values to get the right totals (and get you cost estimations correct). Neither litellm nor AG2 (out of recently used LLM libs) adjust the reported usage for that Grok's quirk. Grok API provides a compatible OpenAI endpoint. For reasoning models the didn't invent the wheel and use the standard reasoning_effort parameter just like OpenAI does with its' o1/o3/o4 models. Yet for some reasons xAI decided to deviate from OpenAI's approach to reasoning tokens accounting. That's unfortunate this inconsistency got into prod API from xAI.  ( 3 min )

This-driven development, that-driven development, and now you should bother with this other thing? I am only half-serious. You should not. Yet you might still want to consider it as a litmus test for your projects. I am not saying that you should use Software Development Kits (SDKs) for development. We all do. Rather, I am asking you to think of your codebase and product as an SDK or part of it. But first, what is all this XYZ-driven development? XYZ simply refers to the guiding principle or artifact that drives the development process. Mind you, this is not necessarily a methodology like "Agile" or "Waterfall", which drive the organization of the development process. I like to think of this distinction as follows: You gather all the developers in a room and organize them to work on a proj…  ( 6 min )

Ever tried using a mobile app that felt... off? Maybe the buttons didn’t respond quite right, or it lagged at the worst moment, like when you were about to hit "confirm" on a payment. Chances are, that app wasn’t built natively. In today’s development world, there’s a lot of noise around frameworks that promise to “build once, run everywhere.” Sounds great, right? But despite the rise of cross-platform tools, there’s a quiet but steady group of developers and companies who still pick native mobile app development, and they’ve got good reasons.

Hoisting is a fundamental concept in JavaScript that often leads to confusion, especially for those new to the language. Understanding how hoisting works can help you write cleaner and more predictable code. This article explains what hoisting is, how it works, and the differences in behavior between various types of declarations. Hoisting is JavaScript’s default behavior of moving declarations to the top of their scope before code execution. This means that variables and functions can be referenced before they are declared in the code. It is important to note that only declarations are hoisted, not initializations. var Variables declared with var are hoisted and initialized with undefined. Consider the following example: console.log(a); // undefined var a = 10; Internally, this is inte…  ( 4 min )

As I started learning Flask, I was building simple apps just to understand the basics and get comfortable with it. Once I felt a bit more confident, I decided to start a project, a site monitoring tool. Since I knew the project would grow and include more functionality, I realized that things should be organized better. That’s when I came across Flask Blueprints. A Blueprint is a modular way to organize code and routes into separate components. Today, I set up my first Blueprint in Flask and here’s how it went. blueprint-example/ ├── run.py └── app/ └── routes.py └── __init__.py └── templates/ └── index.html from flask import Blueprint,render_template #creating a flask blueprint called 'main_route' main_route=Blueprint('main_route',__name__) #define a route on this blueprint @main_route.route('/') def blue_example(): return render_template('index.html') from flask import Flask app=Flask(__name__) def blue_example(): from .routes import main_route app.register_blueprint(main_route)#registering my blueprint to my flask app instance return app from app import blue_example app=blue_example()#Calling a function to get flask app instance if __name__ == '__main__': app.run(debug=True) #run the app in debug mode I basically had an idea of how this works because I had learned about MVC (Model, View, and Controller) in Java. The working process of both is quite similar, so I was able to grasp it a bit quicker. Here are a few things I found helpful about using Blueprints: It's a clean way to split the code logically. For example, separating routes and the dashboard into components makes the structure much easier to work with. It's much easier to manage as the app grows and more features are added. It makes the project more organized and scalable, which is especially useful when working in teams or revisiting the project later.  ( 3 min )

As chatbots become essential in customer service, e-commerce, healthcare, and more, ensuring they function correctly and efficiently has become a top priority. Chatbot testing ensures that conversations are accurate, context-aware, and provide a seamless user experience. Traditional testing methods often fall short due to the complexity and unpredictability of natural language. That’s where Artificial Intelligence (AI) steps in to revolutionize chatbot testing. In this guide, we’ll explore how to test chatbots using AI, examine whether legacy tools can keep up, and outline how automation powered by AI can transform your testing strategy. Can Legacy Automation Tools Handle Chatbots? Here’s why: Lack of Natural Language Processing (NLP) support: Traditional tools can’t interpret or generate human language.

Generating large random numbers is a common requirement in programming, especially in applications requiring strong randomness. The standard rand() function in C generates pseudo-random numbers, which often fall short in range and size for many applications. In particular, generating unsigned long long random numbers can be challenging, especially if you find that the outputs of rand() are not sufficiently large and they often exceed certain thresholds. Why the Standard rand() Does Not Meet Your Needs The rand() function is designed for simplicity and it typically returns a value in the range from 0 to RAND_MAX, which is defined in stdlib.h. The maximum value returned by rand() is often just 32767, making it unsuitable for generating large random numbers like those represented by an unsign…  ( 5 min )

I worked for a FAANG company for a bit, and one thing that surprised me was just how many tasks were manual. How noticeably patchy the tooling and automation coverage was. But also very obviously their tooling and automation was state of the art and much more sophisticated than small tech. But I think there's basic math at play. If I work at a small company and have 100 things, and 50% are automated, then I need say 50 engineers to handle the workload. But if I work at big tech, and there are 100,000 things, and 75% are automated, then I need 25,000 engineers to handle the workload. There's also the algorithm optimization. While I think alogrithmic optimizations will trickle down, and that's good. For (AlphaEvolve)[https://news.ycombinator.com/item?id=43985489] to have a 1% speedup in most small to medium size businesses. Fine, but that's not worth spending a lot of time on. But for AlphaEvolve to have a 1% speedup at google? May save millions of dollars. The point of which is to say, there's probably lots of ways that this will trickle down to every day users, and software engineers across the board may see more and more of their tasks automated, but a continuous truism in the industry is that what works for big tech often doesn't work for you medium-sized MSP. This might explain the difference between why Google says that AI can write 30% of it's code, and medium sized business struggle to get it to work. There's just a lot less boilerplate to right at medium sized businesses. At google, being able to automatically upgrade a node.js dependency may literally impact thousands of microservices, saving thousands of engineering hours. At your company it might save a few hours, if it doesn't take longer than that to get it going in the first place.  ( 3 min )

As the web continues to evolve, the need for faster, more efficient communication between browsers and servers has driven the development of modern protocols. HTTP/1.1, introduced in 1997, served the web for nearly two decades. But with increasing demand for speed, efficiency, and performance, HTTP/2 emerged as a much-needed upgrade. Let’s explore the major differences between these two protocols in a clear, visual, and easy-to-understand way. HTTP/1.1 is a text-based protocol that works on a request-response model. While it has served its purpose for years, it has several limitations: Sequential Requests: Only one request is allowed per TCP connection at a time, leading to blocking. Multiple Connections: To fetch multiple resources, browsers open multiple TCP connections, which increases …  ( 3 min )

Setting cookies in TypeScript can often lead to unexpected behavior, especially when different methods are applied. If you've been trying to set cookies but have faced inconsistencies or errors, you're not alone.

I have this idea for a web-based music app, basically an in-browser DAW. The question of whether or not "AI is Creative" is somewhat unknowable, but I think there are certain sort of mathematical / combinatorial observations one can make about innovation. The Library of Babel is a short story by Jorge Luis Borges that presents a universe in the form of a vast library containing all possible books of a certain format. The library contains every possible arrangement of letters, spaces, and punctuation marks, meaning it holds not just every book ever written, but every book that could ever be written - including all possible variations with typos, nonsense, and meaningless combinations of characters.

🗥️ So I was casually doomscrolling X (yes, again)... when I stumbled upon a post by DEV Community that made my brain short-circuit: ✨ “ScoutDB turns plain English into MongoDB queries.” Wait, what?! You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer. No more $lookup headaches. No more crying in JSON.

Elm’s type system lets you write clear, correct code without the clutter of explicit type annotations. Its friendly compiler not only infers types automatically but also provides helpful error messages that guide you toward writing sound code. In this post, we'll explore practical examples that highlight how Elm’s type inference and compiler feedback enhance code correctness and simplify your development experience. When coding in Elm, the compiler deduces the types of values based on their usage. This lets you focus on application logic rather than on managing repetitive type declarations. Consider a simple arithmetic function: square x = x * x Since the multiplication operator (*) applies only to numbers, Elm infers that x must be a number. No extra annotations are needed, keeping y…  ( 5 min )

When people create new accounts, it’s normal for you to need a way of contacting them with onboarding information, billing alerts, and more. That’s why having the right email address is so important. However, what if they made a typo when providing the email address? Or they simply want to create an account without any real interest in using the service as intended? In either case you’ll want to verify that they can access the email address they’ve given you. The simplest approach adopted by most is to send a unique link in an email to that address, and have a user click on that link to verify their account. It’s simple, but it works. But how can you test this kind of workflow with Selenium? Why can’t Selenium test this already? While Selenium is an extremely capable tool for testing web c…  ( 4 min )

Every morning I gift myself 90 mins to work on anything I desire. Sometimes I read interesting books (1, 2, 3, 4), other times I learn new skills (5, 6) but most times I work on programming projects. For a long time now those programming projects have been Elm related. What can I say? I simply enjoy using Elm. I've tried to share my knowledge along the way by taking the time to reflect on what I've done and by writing about it from my perspective. On many occasions I just shared the work and put off sharing my thoughts about the work for so long that it became a chore to write about it. Reflecting and writing about my programming selfishly helps me improve my software development skills. Writing in public forces me to think more deeply about what I'm doing and why I'm doing it such that it gives me a richer understanding of my craft. A positive side effect is that what I share could also potentially help others. Though, I try to temper my hubris and not fool myself into thinking that random people on the internet actually care about what I have to say. Given that I sometimes don't share and write about my work as often as I'd like and that I think sharing and writing about my work helps myself and others, I've decided to start a new series on this blog called "Diary of an Elm Developer". It's a way for me to give myself permission to share more frequently about my Elm related excursions in an open and freer format. I'm feeling excited about this new series. Stay tuned! If you're interested in improving your skills with Elm then I invite you to subscribe to my newsletter, Elm with Dwayne. To learn more about it, please read this announcement.  ( 3 min )

Hello DEV community 👋 My name is Alireza Minagar, and I come from a rather unique background — as a neurologist, researcher, and now a software engineering student. After years of diagnosing complex neurological conditions, I’ve begun exploring how artificial intelligence and software can revolutionize healthcare. Surprisingly, many skills from my medical background translate directly into programming. Here are 5 lessons from neurology that shape how I now think about software engineering: In medicine, we never treat a symptom without understanding its root cause. Debugging works the same way — don’t guess. Investigate. Analyzing EEGs or MRIs is about spotting patterns. Writing efficient code or identifying logical bugs requires the same cognitive muscle. Whether prescribing medication or defining logic in code, tiny errors can lead to serious consequences. Precision builds trust — in both healthcare and software. Medical professionals live by notes. In code, comments, READMEs, and clear commit messages keep everything healthy and maintainable. In both medicine and tech, decisions have real consequences. Transparent, explainable algorithms are just as vital as informed consent. I’m currently learning Python, full-stack engineering, and bioinformatics with the goal of contributing to healthcare-focused AI solutions. Let’s build a world where medical insight and machine logic support — not replace — human care. — Alireza Minagar, MD, MBA, MS LinkedIn: linkedin.com/in/alirezaminagar Medium: medium.com/@aminagar_38889  ( 3 min )

For the longest time, the "separation of concerns" has been the ultimate guiding principle of software engineering. We thus structure our codebases accordingly: Grouping related files by responsibility; Partitioning logic by technical layers; And sometimes even isolating by programming language.1 Popular architectural patterns such as the Model-View-Controller (MVC) have applied and codified this principle to the point of dogma. Universities, bootcamps, and courses everywhere teach and perpetuate the notion that the MVC architecture is the be-all and end-all of architectural patterns. To be fair, the MVC architecture is indeed often the correct mental model for fathoming any CRUD-heavy application (i.e., virtually 99.9% of web applications2) because it formalizes the flow of data from t…  ( 6 min )

Last year, I intensely started using AI (LLM) tools and caught a terrible wave of sadness and melancholy after 5–6 months of use. For me, the most difficult thing wasn’t that an LLM could write code in general, but the realization that, in fact, it’s not that important. A much more significant abstract question arose: why even write it if everything could change so quickly tomorrow that you wouldn’t even blink? After feeling down and literally being sick of it, and wandering through bookstores, I stumbled upon an interesting book — “The Art of Excellent Products: Enchanting Customers with Premium Brand Experiences” by Riccardo Illy. And this book resonated so deeply that I understood how to resolve (for the time being) the moral dilemma with AI code, when you don’t write the code yourself,…  ( 4 min )

Sony’s eyeing another round of PS5 price hikes after warning that new US tariffs could hit it to the tune of roughly ¥100 billion (£513 million). Despite sitting on three months’ worth of US stock, the console maker is “evaluating” whether to pass those extra costs on to gamers. It’s already bumped the digital PS5 up by £40/€50 across the UK, Europe, Australia and New Zealand this spring, on top of previous—and even steeper—price rises in Japan. To dodge ongoing tariff roulette, Sony exec Hiroki Totoki said shifting some PS5 production to the US “needs to be considered going forward” as an “efficient strategy.” No US price hikes have landed yet, even as rivals like Microsoft and Nintendo tweak their own hardware costs in response to the same trade tangle.  ( 3 min )

TL;DR: Doom The Dark Ages might be a blast on PC and consoles, but on Steam Deck it’s straight-up “nightmare” territory. Even with XeSS Quality set to low and resolution cranked down to 1280×720 (and later 960×540), SteamDeckHQ could barely eke out 30 FPS in open areas—and those dips into the mid-20s make everything blurry, pixelated and generally unplayable. If you’re eyeing the Deck as your go-to, steer clear—for now at least. Patches might improve performance down the line, but there’s no guarantee. If you want demon-slaying glory without constant frame-rate faceplants, stick to PC, PS5 or Xbox Series X/S.  ( 3 min )

After getting bumped from late 2025 to May 26, 2026, GTA 6 still isn’t locked in—Bloomberg insider Jason Schreier warns there’s “no guarantee” Rockstar will hit that window. The first delay already sent panic through the industry, with other developers shifting their own launches to dodge the Grand Theft Auto onslaught. While a second slip hasn’t been announced, rival studios and especially PC players are bracing for more slippage—meaning even when consoles finally get the game, the PC port could be pushed way further down the road.  ( 3 min )

TL;DR: Steve Downes, the legendary voice of Master Chief, is rallying Halo fans to back the 10-month-long SAG-AFTRA video game voice actors strike. The crux of the dispute? AI voice replication—actors want control over if and how their voices are used, not a blanket ban on AI. Downes (joined by Cortana’s Jen Taylor and veteran Jennifer Hale) stresses, “We’re not against AI, just its misuse,” and urges gamers to make some noise until the “Last, Best, and Final” offer on the table addresses those AI concerns. After other issues found middle ground, this remains the sticking point that could make or break a deal.  ( 3 min )

Meta’s new gig: get paid to smile, squat, and chat Meta has quietly kicked off “Project Warhol,” a data-collection effort run through Appen, that pays participants $50 an hour to record facial expressions, body movements (think squats), and even small talk.

TL;DR: Google DeepMind’s new AI agent, AlphaEvolve, teams up with Gemini LLMs and an evolutionary test-and-refine loop to invent entire computer algorithms—and it’s already live inside Google’s infrastructure. It’s boosted Borg cluster efficiency by 0.7%, trimmed bits off TPU circuits, and even sped up Gemini model training kernels by 23% (cutting overall training time 1%), all while churning out human-readable code. But AlphaEvolve isn’t just optimizing data centers—it’s smashing math records. Using its gradient-based evolution, it beat Strassen’s 56-year-old 4×4 matrix-multiply record, improved 14 algorithms, and tackled 50+ open problems (nailing or improving 75% of them), including setting a new 11-dimensional “kissing number” high score. With its plug-and-play approach, DeepMind hopes to spin out breakthroughs in material science, drug discovery, and beyond.  ( 3 min )

There is a good chance that when you hear "San Francisco," you immediately think of cable cars. These moving national landmarks have been continually operating since 1873. This technology relies on tracks and a robust underlying cable technology, mostly hidden away from the public eye. This made SF the perfect backdrop for conversations about a modern technology that needs tracks and guardrails: agentic AI.  If there was a common thread among the conversations at this year's RSA Conference, it was the emergence of agentic AI as an operational "colleague," not just a tool.

Performance matters — especially when dealing with large-scale systems or performance-critical code. Go (Golang) provides first-class support for benchmarking via the testing package. This article walks you through the fundamentals of benchmarking in Go: what it is, why it's important, and how to run benchmarks to compare multiple functions. Benchmarking is the process of measuring how efficiently a piece of code executes. In Go, this typically involves determining how long a function takes to run, how many resources it uses, or how well it scales under load. Benchmarking is different from testing — it doesn’t check if your code is correct but it checks how well it performs. Benchmarking is useful when you want to: Compare different implementations of the same logic (e.g., using + vs strin…  ( 4 min )

It starts the same way every time: an RSS feed, a CSV dump, a dashboard wired together with hope and duct tape. Maybe the data’s late. Maybe the moving average lags just enough to miss the signal. Or maybe it’s just another system straining under the weight of “real-time” without the architecture to back it up. In this tutorial, we’ll build something better. Using Spring Kafka, we’ll stream simulated live stock data into a Kafka topic. From there, Kafka Streams will compute the Relative Strength Index (RSI) on the fly, and we’ll persist it to MongoDB using Spring Data MongoDB. On the historical side, we’ll use MongoDB’s aggregation framework to calculate and analyze simple and exponential moving averages (SMA and EMA) using the MongoDB aggregation pipeline—no third-party data warehouse req…  ( 24 min )

The term RAG (Retrieval-Augmented Generation) refers to a hybrid AI framework that combines information retrieval (like Googling) with large language models (LLMs) to deliver accurate, context-aware answers. Unlike traditional LLMs that generate responses based solely on pre-trained knowledge, RAG grounds its answers in real-time, external data, minimizing errors and hallucinations. Why RAG Matters LLMs like GPT-4 excel at generating text but face limitations: Static knowledge: They can’t access up-to-date or domain-specific data. Hallucinations: They may invent plausible-sounding but incorrect facts. RAG solves this by dynamically retrieving relevant information before generating a response, ensuring answers are factual, current, and contextually grounded. How RAG Works: A 2-Phase Proc…  ( 4 min )

First of all, I want to extend a heartfelt thank you for all the support you showed during my successful series of 20 weekly articles on distributed systems, which I completed in March. I will occasionally post articles on distributed systems if I come across topics that should be added. Your engagement and feedback have been incredibly motivating, and I'm excited to announce my next series on Dev.to! Starting this Sunday, I will be launching a new series focused on system design, inspired by the book Righting Software by Juval Löwy. This book is divided into two parts: system design and project design. My series will concentrate on the system design aspect. Weekly Articles: Every Sunday, I will release a new article that delves into various system design techniques and principles. We will dive into the real world examples. Comprehensive Coverage: While the book will serve as a reference, it is not necessary to have it. My articles will cover almost everything you need to know. Practical Insights: You will learn an amazing system design technique that I personally find invaluable. I use it in all my projects, whether they are small or large, professional or personal. Hands on: I will also try to deliver some hands on projects where people following will dive deeper into the concepts. I had the privilege of attending a System Design cohort led by Jeff Doolittle. The insights and knowledge I gained from that experience, combined with my day-to-day work on real-life systems, will be reflected in this series. I am committed to delivering the most valuable content, drawing from both the book and my practical experiences. Stay tuned, and don't forget to follow me to get the latest updates! Thank you once again for your support. Let's embark on this exciting journey of mastering system design together!  ( 3 min )

Having too few people with deployment authority reduces software delivery performance. Developer experience and burnout may have put platform engineering in the spotlight, but focusing on continuous delivery will likely improve developer experience (DevEx) the most at your organization. There is, however, a speed bump ahead for those automating their deployment pipeline: deployment gatekeepers. If you don’t increase the number of people with deployment authority, you’ll miss many of the benefits of continuous delivery. A single deployment gatekeeper will lower your chances of getting a return on your investment within the first 100 days and permanently limit your software delivery performance.

Due to project requirements, we needed the data quality module, which offers excellent data quality monitoring capabilities for data warehouses. Therefore, we decided to upgrade from the existing 2.0 version to 3.0 or above. We tested both versions 3.0.1 and 3.1.1 by running identical task scheduling operations such as pausing tasks. In the end, we chose version 3.0.1. Reasons: When testing SQL tasks in 3.1.1, launching hundreds of SQL tasks simultaneously caused errors that prevented many tasks from running properly. After consulting the community experts, it was confirmed to be a bug in DolphinScheduler. Although this issue occasionally appears in 3.0.1 as well, it is much less frequent.

A couple of months ago I joined CloudRift, tagging along my long time peer Dmitry in his new venture. One of the first things that came up was setting up log aggregation — something many projects start without, but quickly realize they need after spinning up more than one server. It should be a mundane task after having done this a few times, but yet again, there is a twist and something new to discover. I pull out my usual cards and start with ELK, since even though there are serious contenders out there, I still find Kibana unbeatable, and most people love it. CloudRift deploys its agents on pools of nodes which in turn communicate with an orchestrator that acts as a centralized resource broker.

In the world of digital marketing and SEO, we often focus heavily on content, backlinks, and keywords. However, one often overlooked factor is server management—a technical area that has a surprisingly significant impact on site performance and rankings. Google considers page speed and uptime when ranking websites. If your site takes too long to load or frequently goes down, your rankings can be negatively affected. Some of the key server-side factors that influence SEO include: Server response time (TTFB) Downtime or hosting issues Poor load balancing or caching strategies Misconfigured SSL or redirects These aren't typically in an SEO’s toolkit, but they have direct consequences. Recently, while working with a client whose site was experiencing random slowdowns, we discovered the issue was rooted in unmanaged server processes consuming too many resources. After a server audit and implementing best practices (including log rotation, performance monitoring, and scaling strategies), we saw a measurable improvement in Core Web Vitals and a 12% increase in organic traffic in 3 weeks. For those unfamiliar with these tasks, there are server management teams that handle these backend operations seamlessly, allowing businesses to focus on growth while maintaining technical health. SEO isn't just about keywords and content. If you're ignoring server-side optimization, you're leaving potential growth on the table. Collaborating with developers and sysadmins—or understanding their pain points—can give you a competitive edge in search results. Have you ever encountered server issues that affected your SEO performance? Let's discuss in the comments.  ( 3 min )

We're excited to share some awesome news from RailsFactory! Meet Cloud Attachment Pro - a fresh, community-driven Redmine plugin developed by our brilliant team member, Sivamanikandan.

In Object-Oriented Programming (OOP), HAS-A and IS-A relationships are fundamental concepts used to describe how classes and objects relate to each other. While these apply to many OOP languages like Java or C#, the principles are universal. IS-A Relationship (Inheritance) Represents: A subtype relationship (child → parent) Mechanism: Achieved through inheritance. Implies: The derived class is a type of the base class. Usage: Use when there’s a clear hierarchical relationship. public class Animal { public void Eat() => Console.WriteLine("Eating..."); } public class Dog : Animal { public void Bark() => Console.WriteLine("Barking..."); } // Usage Dog dog = new Dog(); dog.Eat(); // Inherited dog.Bark(); // Dog-specific Dog IS-A Animal. HAS-A Relationship (Composition) Represents: A class containing references to other classes as members. Mechanism: Achieved through composition (member variables). Implies: A class has a reference to another class. Usage: Use when one object uses another. public class Engine { public void Start() => Console.WriteLine("Engine starting..."); } public class Car { private Engine engine = new Engine(); public void StartCar() { engine.Start(); Console.WriteLine("Car started."); } } // Usage Car car = new Car(); car.StartCar(); Car HAS-A Engine. Aspect IS-A HAS-A Meaning Inheritance (child ← parent) Composition (class contains) Implementation class B : A {} class A { B b; } Example Dog : Animal Car has Engine Use Case Reuse behavior via inheritance Delegate tasks via composition Polymorphism Supported Not directly Prefer composition (HAS-A) over inheritance (IS-A) when possible (favor delegation for flexibility). Use IS-A only when the subclass truly fulfills the contract of the superclass (Liskov Substitution Principle).  ( 3 min )

I continue to take care of my Home Assistant. This week, I replaced my original setup with Cloudflare Tunnel. My usage of Home Assistant required external access from the beginning. I achieved it in two steps: I created a subdomain of frankel.ch, which pointed to my router's external IP. On my router, I opened a dedicated port. In turn, the router forwarded requests to my HA. The next action was to secure connections via an SSL certificate. I initially aimed for mTLS, but I couldn't achieve it because the iPhone HA application doesn't support it. However, encrypted communication to my server was a hard requirement. The good news is that the times when SSL certificates were a luxury feature are gone.

I was amazed—until it struck me one day that while I kept talking about "clean code" and "modern stacks," the rest of humanity was writing about AI, shipping publicly, and narrating about self. My brand did not reflect my growth. It reflected what I was yesterday. And that's when I knew: Why Personal Branding Is No Longer Optional in Tech And unlike resumes or portfolios, personal branding isn't permanent. But the shocker is this: 5 Ways to Future-Proof Your Personal Brand Rebuild Your Brand Every Quarter A…  ( 5 min )

Introduction For system administrators, surprises are rarely a good thing. Whether it's a sudden spike in CPU usage, memory running dangerously low, or disk space nearing its limit, these issues can quickly escalate into major problems : from system slowdowns to full outages. 1. Why monitor your server every minute? When it comes to server health, timing is everything. Even a few minutes of downtime can have serious consequences… from lost revenue to broken user trust. While traditional monitoring solutions may check system status every 5 or 10 minutes, some environments require faster feedback and immediate awareness. a. Real-Time awareness b. Faster incident response c. Lightweight alternative to complex monitoring tools d. Ideal for headless or remote servers 2. What metrics should …  ( 8 min )

The D programming language, commonly known as DLang, offered a fresh perspective on system-level programming by blending familiar features of C++ with modern mechanisms to enhance code safety, simplicity, and performance. Created by Walter Bright, it is meant to be a viable alternative to C++ for developers seeking to improve productivity and code safety while maintaining the low-level control that C++ offers. DLang is a general-purpose, statically typed programming language with many parallels to C++. Like C++, it supports object-oriented programming, manual memory management and systems programming. However, DLang builds on these fundamentals by introducing features that mitigate some of the complexities and pitfalls of C++, like garbage collection. If you didn't see the first article of…  ( 12 min )

Unit Test Unit testing is a type of software testing where individual units or components of a software are tested in isolation. The purpose is to validate that each unit of the software performs as expected. A unit is the smallest testable part of an application, such as a function, method, or class. Arrange-Act-Assert(AAA) is a simple and effective pattern for writing clear and structured unit tests: Arrange-set up the necessary objects and state, Act-perfom the action you want to test, Assert-verify that the action produced the expected result. Commenting the AAA phases is recommended, especially during learning, in shared codebases, or for more complex test cases. It improves readability, consistency, and maintainability of tests. The scope of unit tests typically focuses on classes …  ( 5 min )

Ever wanted to animate something on scroll without reaching for JavaScript? Well, good news: modern CSS has a new trick up its sleeve called animation-timeline: scroll() — and it’s surprisingly powerful. Let me show you what it is, how it works, and why you might want to use it in your next project. ⸻ 🌀 What Is animation-timeline: scroll()? Traditionally, CSS animations run on a timeline based on time (seconds, milliseconds, etc.). But with this new feature, the animation is synced to the scroll position of an element. That means: the more you scroll, the further along the animation progresses — and when you stop scrolling, the animation pauses too. No JavaScript. No ScrollTrigger. Just clean CSS. ⸻ ✏️ A Simple Example Here’s a quick setup I made: <div id="square"…  ( 5 min )

Let's add validation using Joi to our existing Node.js + Express blog API, specifically for creating articles. npm install joi Create a file: middlewares/validateArticle.js const Joi = require('joi'); // Define the schema const articleSchema = Joi.object({ title: Joi.string().min(3).max(100).required(), content: Joi.string().min(10).required(), author: Joi.string().min(3).required() }); // Middleware to validate request body function validateArticle(req, res, next) { const { error } = articleSchema.validate(req.body); if (error) { return res.status(400).json({ error: error.details[0].message }); } next(); } module.exports = validateArticle; It checks that: title is a string between 3–100 chars content is at least 10 chars author is required and at least 3 chars If validation fails, it sends a 400 response with a message like: "title" is not allowed to be empty In your route file (or server.js, depending on your structure): const express = require('express'); const mongoose = require('mongoose'); const cors = require('cors'); const Article = require('./models/article'); const validateArticle = require('./middlewares/validateArticle'); const app = express(); app.use(express.json()); app.use(cors()); // POST with validation middleware app.post('/api/articles', validateArticle, async (req, res) => { try { const newArticle = new Article(req.body); const savedArticle = await newArticle.save(); res.status(201).json(savedArticle); } catch (err) { res.status(500).json({ error: 'Server error while creating article' }); } }); { "title": "How to Use Joi", "content": "Joi is a powerful schema description and validation tool...", "author": "Xavier" } { "title": "", "content": "short", "author": "" } Response: { "error": "\"title\" is not allowed to be empty" }  ( 3 min )

As LLMs like ChatGPT, Gemini, and Grok soar in popularity, the Spiderly library stands out by addressing what they can’t yet fully handle: project architecture that demands a broader perspective and deeper understanding. Developers leaning heavily on LLMs without grasping the generated code are more prone to errors that, if they slip into production, take longer to fix. Spiderly minimizes those risks. With Spiderly.CLI tool you create a solid foundation with whole app structure, email auth, Google auth, logging etc. Then, the Entity Administration Source Generator builds everything you need for entity management. From there, you focus your brainpower on solving the end user’s specific problems. The star of Spiderly is its Entity Administration Source Generator (Spiderly.SourceGenerators project), a standalone tool. It delivers: Easily customizable, responsive admin forms for entities on the client side Client-side form validations and server-side object validations for incoming client data Controller methods for both client and server Flexible authorization methods Server-side CRUD methods for entity administration Methods for filtering and working with tables Spiderly also tackles other essentials: authentication (client and server, using JWT tokens), API request rate limiting, logging, entity versioning, consistent database table naming, and client-side app layout design. I’d love for this, open-source project to spark a community that sets a standard for solving general coding challenges worth tackling broadly. Right now, Spiderly focuses on web apps using C#, Azure, EF Core (Lazy Loading), Serilog, JWT, FluentValidation, Mapster, SQL Server, Angular, and PrimeNG. Spiderly website: https://www.spiderly.dev, Check out a 4-minute demo of building an app with Spiderly.CLI: https://youtu.be/t3TfUmnKUI4?si=rpjSupNyQVd_nS2J Spiderly library source code: https://github.com/filiptrivan/spiderly Example app using Spiderly: https://github.com/filiptrivan/plenum-rmt Let’s build something great together!  ( 4 min )

The Art of Clean React: Principles for Maintainable Components 🎨 Single Responsibility Principle (SRP): One Job, One Component 🎯 Just like functions should do one thing well, so should your components. A component should ideally have a single, well-defined purpose. If a component starts handling too many responsibilities (managing multiple unrelated states, fetching diverse data, rendering complex unrelated UI), it becomes harder to reason about and more prone to breaking.   Bad Example (Multiple Responsibilities): Imagine a component that fetches user data and handles form submissions for a new address. Good Example (Separated Responsibilities): Break this down into two components: one responsible for fetching and displaying user data (UserProfile), and another for handling the address…  ( 5 min )

Images are an essential part of the web. They inform, engage, and enhance the overall user experience. But what happens when an image fails to load, or when a user cannot see it? That’s where the humble alt attribute of the tag comes into play, serving as a vital link between visual content and universal accessibility. The alt attribute in HTML provides alternative text for an image. This text is displayed if the image cannot load. More importantly, it is read aloud by screen readers, helping visually impaired users understand the content and context of images. alt Attribute Important?

The most surprising part is probably that they are proud of removing parts in a brand new version. I view it as an excellent sign of maturity. The subtitle of Rails 8 is "no PaaS required", but they could have also said : "No React required", "No Redis required", and so on. What a relief. Any shiny new framework is proud about "what's new under the sun", not "what's deleted to simplify devs life". The first excellent part is what didn't move.

What Are Computer Networks? A computer network is a group of interconnected devices that can communicate and share resources. Think of it as the digital nervous system that connects computers, phones, servers, and more—allowing data to flow like information highways. Used in homes, schools, and offices. Connects devices in a small area. Covers a large geographic area. The Internet is the biggest WAN. Covers a city or a large campus. Larger than LAN but smaller than WAN. Your Bluetooth devices form a PAN—like your phone and earbuds. Router: Directs data packets between networks. Switch: Connects multiple devices in a LAN. Modem: Connects to your ISP and provides internet access. Access Point: Enables wireless devices to connect to the network. Server & Client: Server provides, client consumes services/data. Physical Data Link Network Transport Session Presentation Application Each layer has a specific role—from moving bits to enabling web apps. More practical and used in real-world networking: Link Internet Transport Application HTTP/HTTPS – Web browsing FTP/SFTP – File transfers SMTP/IMAP/POP3 – Email TCP/UDP – Data transport IP – Routing and addressing DNS – Resolves domain names to IPs Whether you're streaming Netflix, sending a meme, or backing up your files to the cloud—computer networks make it all happen. They're the silent enablers of our digital lives. 🧠 Fun Fact: The first message ever sent over the ARPANET (the Internet’s ancestor) was "LO"—they meant to type "LOGIN" but the system crashed! Stay tuned, stay connected, and maybe ping your friend instead of ghosting them. Tools That Help: Wireshark, Cisco Packet Tracer, Netcat, Nmap, and a whole lot of curiosity.  ( 3 min )

What is a Callback? A callback is a function passed into another function, to be called later when something happens or a task is finished. Analogy: Imagine you order food and give the restaurant your phone number so they can call you when your food is ready. Your phone number is the callback. JavaScript is single-threaded and often needs to wait for things (like loading data or waiting for a user action). Instead of stopping everything, it uses callbacks to say, “Do this later, when the waiting is done.” function doSomethingLater(callback) { console.log("Doing something..."); callback(); } function sayHello() { console.log("Hello, I'm the callback!"); } doSomethingLater(sayHello); Output: Doing something... Hello, I'm the callback! doSomethingLater(function() { console.log("This is an inline callback!"); }); setTimeout and setInterval setTimeout(function() { console.log("This runs after 2 seconds"); }, 2000); Event Listeners button.addEventListener('click', function() { console.log("Button clicked!"); }); Fetching Data (with Promises, but still uses callbacks) fetch('https://api.example.com/data') .then(function(response) { return response.json(); }) .then(function(data) { console.log(data); }); Callbacks are not always asynchronous. Some callbacks are called right away. Callbacks are just functions. There’s nothing special about them except how they’re used. Callback Cheat Sheet Definition: A callback is a function you pass to another function to be called later.

However, ordering the results by criteria such as commit date can greatly enhance your workflow and help you find the most relevant information. In this article, we'll explore how to achieve that by combining git grep with other Git commands. Understanding Git Grep git grep is a powerful command that allows you to search for specific text patterns in your Git repository. It's faster than traditional grep because it uses Git's indexing functionality. However, by default, the results are simply listed without any order based on the commits.
